Question

Автомобиль шёл 2 ч со скоростью 56 км/ ч и 3 ч со скоростью на 9 км/ч меньше первоначальной.найди расстояние пройденное автомобилей

Answer 1

2*56=112 км проехал первоначально
56-9=47 км/ч ехал потом
3*47=141 км проехал за 3 часа
141+112=253 км проехал автомобиль.

Answer 2

Calculation of Distance Traveled by the Car

To calculate the distance traveled by the car, we need to find the total distance covered during each leg of the journey and then add them together.

Let's break down the problem step by step:

1. The car traveled for 2 hours at a speed of 56 km/h. 2. The car then traveled for 3 hours at a speed 9 km/h less than the initial speed.

To find the distance traveled during each leg, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled during each leg:

1. Distance traveled during the first leg: - Speed = 56 km/h - Time = 2 hours - Distance = 56 km/h × 2 hours = 112 km

2. Distance traveled during the second leg: - Speed = 56 km/h - 9 km/h = 47 km/h (since the speed is 9 km/h less than the initial speed) - Time = 3 hours - Distance = 47 km/h × 3 hours = 141 km

Now, let's calculate the total distance traveled by adding the distances from both legs:

Total distance = Distance of the first leg + Distance of the second leg = 112 km + 141 km = 253 km

Therefore, the total distance traveled by the car is 253 km.
