Question

1) Пешеход идёт со скоростью 50 м/мин,а скорость велосипедиста в 3 раза больше скорости пешехода. Велосипедист и пешеход одновременно отправились с остановки на станцию.На сколько километров обгонит велосипедист пешехода за 2ч?

Answer 1

50м/мин *120мин(2часа)=6000м=6км
150м/мин*120мин =18000м=18км
18км-6км=12км - на 12 обгонит велосипедист пешехода за 2часа.

Answer 2

50×3=150м/мин скорость велосипедиста
150-50=100м/мин скорость отрыва
100×2 =200метров
200метров=0,2 километра

Answer 3

Calculation of the Distance the Cyclist Overtakes the Pedestrian

To calculate the distance the cyclist overtakes the pedestrian, we need to determine the relative speed between them and the time it takes for the cyclist to overtake the pedestrian.

Given: - The pedestrian's speed is 50 m/min. - The cyclist's speed is 3 times the pedestrian's speed.

To find the relative speed between the cyclist and the pedestrian, we subtract the pedestrian's speed from the cyclist's speed: Relative speed = Cyclist's speed - Pedestrian's speed = 3 * 50 m/min - 50 m/min = 100 m/min.

Now, we can calculate the distance the cyclist overtakes the pedestrian in 2 hours using the formula: Distance = Speed * Time.

Substituting the values: Distance = 100 m/min * 2 hours = 200 m/min * 60 min/hour = 12,000 meters.

Therefore, the cyclist will overtake the pedestrian by a distance of 12,000 meters in 2 hours.
