Question

Чертеж этой задачи .Машина прошла расстояние между городами за 5 часов , идя со скоростью 48км/час.обратный путь она прошла за 6 часов .На сколько км/час скорость машины на обратном пути была меньше?

Answer 1

1) 48*5=90(км) проехала машина на 1 путь
2) 90:6=15(км)
Ответ:на 15 км меньше

Answer 2

Solution:

To find the difference in the speed of the car on the return trip, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the car on the forward and return trips.

1. Forward Trip: - Time = 5 hours - Speed = 48 km/h - Using the formula, we can calculate the distance covered on the forward trip: - Distance = Speed * Time - Distance = 48 km/h * 5 h - Distance = 240 km

2. Return Trip: - Time = 6 hours - We need to find the speed on the return trip. - Using the formula, we can calculate the speed on the return trip: - Speed = Distance / Time - Speed = 240 km / 6 h - Speed = 40 km/h

Answer:

The speed of the car on the return trip was 8 km/h less than on the forward trip.
