Question

Автобус едет 6 ч со скоростью 70км/ч , а автомобиль проезжает это же расстояние со скоростью 84км/ч. На сколько часов дольше едет автобус

Answer 1

1)6*60=360 км.
2)360/90=4 часа.
3)6-4=2 часа.

Answer 2

Calculation of Time Difference

To calculate the time difference between the bus and the car, we need to determine the distance traveled by both vehicles and divide it by their respective speeds.

Let's assume that the distance traveled by both the bus and the car is the same.

The bus travels for 6 hours at a speed of 70 km/h, while the car travels the same distance at a speed of 84 km/h.

To find the time difference, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken by the bus and the car separately.

Time taken by the bus:

Distance = Speed * Time Time = Distance / Speed

Given that the bus travels for 6 hours at a speed of 70 km/h, we can calculate the distance traveled by the bus:

Distance = 70 km/h * 6 hours = 420 km

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

Time taken by the bus = Distance / Speed = 420 km / 70 km/h = 6 hours

Time taken by the car:

Given that the car travels the same distance at a speed of 84 km/h, we can calculate the time taken by the car:

Time taken by the car = Distance / Speed = 420 km / 84 km/h = 5 hours

Therefore, the car takes 5 hours to travel the same distance that the bus travels in 6 hours.

The car takes 1 hour less than the bus to travel the same distance.
