Question

Из двух пунктов, расстояние между которыми 7км500м, одновременно в одном направлении вышел пешеход со скоростью 6км/ч и выехал автобус. Определите скорость автобуса, если он догнал пешехода через 15мин.

Answer 1

1) 6000/60=100м/мин прошел пешеход
2) 100*15=1500метров прошел пешеход
3) 7500-1500=6000метров проехал автобус
4) 6000/15=400м/минута
Ответ: автобус ехал со скоростью 400 метров в минуту.

Answer 2

To determine the speed of the bus, we can use the formula: speed = distance / time.

Given that the distance between the two points is 7 km 500 m and the pedestrian walks at a speed of 6 km/h, we need to find the speed of the bus.

Let's convert the distance between the two points to meters for consistency: 7 km 500 m = 7,500 m

We are also given that the pedestrian walks at a speed of 6 km/h. To find the time it takes for the pedestrian to cover the distance, we can use the formula: time = distance / speed.

Substituting the values, we have: time = 7,500 m / 6 km/h

To convert the speed from km/h to m/min, we need to divide it by 60: 6 km/h = 6,000 m / 60 min = 100 m/min

Now, let's calculate the time it takes for the pedestrian to cover the distance: time = 7,500 m / 100 m/min = 75 min

We are given that the bus catches up with the pedestrian in 15 minutes. Therefore, the total time it takes for the bus to cover the distance is 75 min - 15 min = 60 min.

Now, we can calculate the speed of the bus using the formula: speed = distance / time. speed = 7,500 m / 60 min = 125 m/min.

Therefore, the speed of the bus is 125 m/min.
