Question

Прохожий заметил идущий на остановку автобус в 180 м позади себя.Чтобы не опоздать, он побежал и через 12 с прибежал на остановку одновременно с автобусом.С какой скоростью пришлось бежать прохожему,если известно,что автобус движется со скоростью 19 м/с?

Answer 1

12*19=228 м путь автобуса до остановки
228-180=48 м путь человека до остановки
48/12=4 м/с скорость человека

Answer 2

Calculation of the Runner's Speed

To calculate the speed at which the pedestrian had to run, we can use the formula:

Speed = Distance / Time

In this case, the distance the pedestrian had to cover is 180 meters, and the time it took for both the pedestrian and the bus to reach the bus stop was 12 seconds.

Using the given information that the bus was moving at a speed of 19 m/s, we can calculate the speed at which the pedestrian had to run.

Speed = Distance / Time = 180 meters / 12 seconds = 15 meters per second

Therefore, the pedestrian had to run at a speed of 15 meters per second to reach the bus stop at the same time as the bus.
