Question

На машине Вася проехал от деревни до города за 3 часа со скоростью 80 км/ч и сделал остановку. После остановки Вася ехал ещё 4 часа. С какой скоростью ехал Вася оставшийся путь, если всё расстояние од деревни до города 600 км?

Answer 1

Ответ:

90 км/ч

Пошаговое объяснение:

1) 3×80=240(км)-проехал Вася за 3 часа

2) 600-240=360(км)-расстояние за 4 часа

3) 360:4=90(км/ч)-скорость

Answer 2

Calculation of Vasya's Speed

To calculate the speed at which Vasya traveled the remaining distance after his stop, we need to determine the time it took him to cover the initial distance and the time he spent on the stop.

Given: - Vasya traveled from the village to the city in 3 hours at a speed of 80 km/h. - Vasya made a stop and then continued traveling for an additional 4 hours.

We can calculate the time Vasya spent on the stop by subtracting the time he spent traveling from the total time elapsed:

Total time elapsed = 3 hours (initial travel time) + 4 hours (additional travel time) = 7 hours

Time spent on the stop = Total time elapsed - Time spent traveling = 7 hours - 3 hours = 4 hours

Now, we can calculate the speed at which Vasya traveled the remaining distance.

Remaining distance = Total distance - Distance traveled during the initial travel time

Given that the total distance from the village to the city is 600 km and Vasya traveled for 3 hours at a speed of 80 km/h, we can calculate the distance traveled during the initial travel time:

Distance traveled during the initial travel time = Speed * Time = 80 km/h * 3 hours = 240 km

Therefore, the remaining distance is:

Remaining distance = Total distance - Distance traveled during the initial travel time = 600 km - 240 km = 360 km

To calculate the speed at which Vasya traveled the remaining distance, we divide the remaining distance by the time spent on the stop:

Speed = Remaining distance / Time spent on the stop = 360 km / 4 hours = 90 km/h.

Therefore, Vasya traveled the remaining distance at a speed of 90 km/h.

Answer

Vasya traveled the remaining distance at a speed of 90 km/h.
