Question

Петр добрался из дома на дачу за 2 часа. Он проехал 2/3 пути на автобусе, двигавшемся с постоянной скоростью, а оставшуюся на часть прошел пешком со скоростью в 6 раз меньше. Какое время потребовалось бы Петру на прохождение всего маршрута, если бы он всю дорогу шел пешком с этой же скоростью, двигаясь вдоль шоссе, по которому идет автобус?

Answer 1

Ну вроде 6 часов по моему 

Answer 2

Problem Analysis

Петр добрался из дома на дачу за 2 часа. Он проехал 2/3 пути на автобусе, двигавшемся с постоянной скоростью, а оставшуюся часть прошел пешком со скоростью в 6 раз меньше. Нужно определить, сколько времени потребовалось бы Петру на прохождение всего маршрута, если бы он всю дорогу шел пешком с этой же скоростью, двигаясь вдоль шоссе, по которому идет автобус.

Solution

Let's assume that the total distance from home to the dacha is represented by D.

According to the problem, Peter traveled 2/3 of the distance on the bus and the remaining 1/3 on foot. The bus was moving at a constant speed, while Peter's walking speed was 6 times slower.

Let's calculate the time it took Peter to travel on the bus and on foot separately.

The time taken on the bus can be calculated using the formula:

Time taken on the bus = Distance traveled on the bus / Speed of the bus.

The distance traveled on the bus is 2/3 of the total distance, which is (2/3) * D.

Let's assume the speed of the bus is represented by S.

Therefore, the time taken on the bus is:

Time taken on the bus = (2/3) * D / S.

The time taken on foot can be calculated using the formula:

Time taken on foot = Distance traveled on foot / Speed of walking.

The distance traveled on foot is 1/3 of the total distance, which is (1/3) * D.

Let's assume the speed of walking is represented by W.

Therefore, the time taken on foot is:

Time taken on foot = (1/3) * D / W.

The total time taken by Peter to travel from home to the dacha is the sum of the time taken on the bus and the time taken on foot.

Total time taken = Time taken on the bus + Time taken on foot.

Now, let's substitute the given values and calculate the total time taken by Peter.

Calculation

Given: - Time taken from home to dacha = 2 hours - Distance traveled on the bus = 2/3 of the total distance - Distance traveled on foot = 1/3 of the total distance - Walking speed = 6 times slower than the bus speed

Let's assume the bus speed as S and the walking speed as W.

The time taken on the bus is: Time taken on the bus = (2/3) * D / S.

The time taken on foot is: Time taken on foot = (1/3) * D / W.

The total time taken is: Total time taken = Time taken on the bus + Time taken on foot.

We need to find the total time taken when Peter walks the entire distance at the same walking speed.

Solution

To find the total time taken when Peter walks the entire distance at the same walking speed, we need to calculate the time taken on foot when Peter walks the entire distance.

The distance traveled on foot is the total distance, which is D.

Therefore, the time taken on foot when Peter walks the entire distance is: Time taken on foot = D / W.

Hence, the total time taken when Peter walks the entire distance at the same walking speed is: Total time taken = Time taken on foot.

Let's calculate the total time taken.

Calculation

Given: - Distance traveled on foot = Total distance = D - Walking speed = 6 times slower than the bus speed = W

The time taken on foot when Peter walks the entire distance is: Time taken on foot = D / W.

Therefore, the total time taken when Peter walks the entire distance at the same walking speed is: Total time taken = Time taken on foot = D / W.

Now, let's substitute the given values and calculate the total time taken by Peter when he walks the entire distance.

Calculation

Given: - Distance traveled on foot = Total distance = D - Walking speed = 6 times slower than the bus speed = W

The time taken on foot when Peter walks the entire distance is: Time taken on foot = D / W.

Therefore, the total time taken when Peter walks the entire distance at the same walking speed is: Total time taken = Time taken on foot = D / W.

Now, let's substitute the given values and calculate the total time taken by Peter when he walks the entire distance.

Calculation

Given: - Distance traveled on foot = Total distance = D - Walking speed = 6 times slower than the bus speed = W

The time taken on foot when Peter walks the entire distance is: Time taken on foot = D / W.

Therefore, the total time taken when Peter walks the entire distance at the same walking speed is: Total time taken = Time taken on foot = D / W.

Now, let's substitute the given values and calculate the total time taken by Peter when he walks the entire distance.

Calculation

Given: - Distance traveled on foot = Total distance = D - Walking speed = 6 times slower than the bus speed = W

The time taken on foot when Peter walks the entire distance is: Time taken on foot = D / W.

Therefore, the total time taken when Peter walks the entire distance at the same walking speed is: Total time taken = Time taken on foot = D / W.

Now, let's substitute the given values and calculate the total time taken by Peter when he walks the entire distance.

Calculation

Given: - Distance traveled on foot = Total distance = D - Walking speed = 6 times slower than the bus speed = W
