Question

Задача. Мотоциклист проехал до места назначения 512,4 км, сделав еще одну остановку. до остановки он был в пути 3 часа и ехал со скоростью 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
512,4-292,8=219,6 км
219,6/2=109,8 км/ч

Answer 2

Problem Analysis

To find the speed at which the motorcyclist traveled after the stop, we need to calculate the distance traveled and the time taken after the stop. We can then use the formula `speed = distance / time` to find the speed.

Calculation

Given: - Distance traveled before the stop: 512.4 km - Time taken before the stop: 3 hours - Speed before the stop: 97.6 km/h - Time taken after the stop: 2 hours

To calculate the distance traveled after the stop, we subtract the distance traveled before the stop from the total distance: Distance after the stop = Total distance - Distance before the stop Distance after the stop = 512.4 km - 512.4 km = 0 km

Since the distance after the stop is 0 km, the speed after the stop is also 0 km/h.

Answer

The motorcyclist traveled at a speed of 0 km/h after the stop.
