Question

Автобус, двигаясь со V=50км/ч проехал то же расстояние, что и автомобиль со V=80км/ч. Автомобиль ехал на 2 часа меньше автобуса скор. времени ехал автобус и скор. автомобиль ​

Answer 1

Ответ:

Представим себе, что автобус вышел за 2 ч до автомобиля

тогда расстояние между ними=100км

скор сближения=80-50=30км/ч

100/30=3 1/3ч=3ч 20мин(машина)

3ч 20 мин + 2 ч = 5 ч 20 мин(автобус)

Answer 2

Calculation of Time and Distance for the Bus and Car

To calculate the time and distance traveled by the bus and car, we can use the formula:

Distance = Speed × Time

Let's assume that the distance traveled by both the bus and the car is represented by 'd'. The speed of the bus is given as 50 km/h, and the speed of the car is given as 80 km/h. The car traveled for 2 hours less than the bus.

Let's calculate the time traveled by the bus and the car:

Time taken by the bus = d / 50

Time taken by the car = d / 80

Since the car traveled for 2 hours less than the bus, we can write:

Time taken by the car = Time taken by the bus - 2

Now, let's substitute the values and solve the equations:

d / 50 = d / 80 - 2

To solve this equation, we can multiply both sides by 400 (the least common multiple of 50 and 80) to eliminate the denominators:

8d = 5d - 800

Simplifying the equation:

3d = 800

d = 800 / 3

Therefore, the distance traveled by both the bus and the car is approximately 266.67 km.

Now, let's calculate the time taken by the bus and the car:

Time taken by the bus = 266.67 / 50 ≈ 5.33 hours

Time taken by the car = 266.67 / 80 ≈ 3.33 hours

So, the bus traveled for approximately 5.33 hours, and the car traveled for approximately 3.33 hours.

Summary:

- The distance traveled by both the bus and the car is approximately 266.67 km. - The bus traveled for approximately 5.33 hours. - The car traveled for approximately 3.33 hours.

Please note that the above calculations are based on the given information and assumptions.
