Question

От города до деревни машина ехала 2 часа со скоростью 56 км/ч. обратно она проехала то же расстояние за 4 ч.с какой скоростью ехала машина на обратном пути?

Answer 1

1) 56×2=112 (км.)-растояние.
2) 112÷4=28 (км/ч.)-обратном пути.

Answer 2

Calculation of the Speed of the Car on the Return Trip

To determine the speed of the car on the return trip, we can use the formula:

Speed = Distance / Time

Given that the car traveled the same distance on the return trip, we can assume that the distance traveled is constant. Let's denote the distance as "d".

On the first trip, the car traveled for 2 hours at a speed of 56 km/h. Therefore, the distance traveled on the first trip is:

Distance = Speed * Time = 56 km/h * 2 h = 112 km

On the return trip, the car traveled the same distance of 112 km, but this time it took 4 hours. To calculate the speed on the return trip, we can rearrange the formula:

Speed = Distance / Time = 112 km / 4 h = 28 km/h

Therefore, the car traveled at a speed of 28 km/h on the return trip.
