Question

Мотоциклист проехал до места назначения 512,4 км, сделав одну остановку. До остановки он был в пути 3 часаи ехал со скоостью 97,6 км/ч. Остальной путь он проехал за 2 часа. С какой скоростью ехал мотоциклист после остановки ?

Answer 1

3*97,6=292,8 км. проехал до остановки
512,4-292,8=219,6 км проехал после остановки
219,6:2=109,8 км.м скорость после остановки

Answer 2

Problem Analysis

A motorcyclist traveled a total distance of 512.4 km, with one stop along the way. Before the stop, the motorcyclist traveled for 3 hours at a speed of 97.6 km/h. The remaining distance was covered in 2 hours. We need to determine the speed at which the motorcyclist traveled after the stop.

Solution

To find the speed after the stop, we can use the formula: speed = distance / time.

Let's calculate the distance traveled before the stop: - Time before the stop: 3 hours - Speed before the stop: 97.6 km/h - Distance before the stop = speed * time = 97.6 km/h * 3 hours = 292.8 km

Now, let's calculate the distance traveled after the stop: - Total distance: 512.4 km - Distance before the stop: 292.8 km - Distance after the stop = Total distance - Distance before the stop = 512.4 km - 292.8 km = 219.6 km

The time taken to cover the distance after the stop is given as 2 hours.

Finally, we can calculate the speed after the stop: - Speed after the stop = Distance after the stop / Time after the stop = 219.6 km / 2 hours = 109.8 km/h.

Therefore, the motorcyclist traveled at a speed of 109.8 km/h after the stop.

Answer

The motorcyclist traveled at a speed of 109.8 km/h after the stop.
