Question

Из одного пункта одновременно в противоположных направлениях отправились велосипедист и пешеход пешеход двигался со скоростью 3 км в час а велосипедист со скоростью в 4 раза большей какое расстояние будет между ними через 2 часа после начала движения ПОМОГИТЕ ПОЖАЛУЙСТА!

Answer 1

1) 3×4=12 км/год
2)3+12=15 км/год
3) 15×2=30 км
Відповідь: 30 км

Answer 2

3*4=12(км/ч) скорость велосипедиста
12+3=15(км/ч) общаяя скорость
15*2=30(км)

Answer 3

Calculation of Distance between the Cyclist and Pedestrian

To calculate the distance between the cyclist and the pedestrian after 2 hours, we need to determine the distances each of them has traveled during that time.

Given: - The pedestrian is moving at a speed of 3 km/h. - The cyclist is moving at a speed 4 times greater than the pedestrian's speed.

To find the distance traveled by the pedestrian after 2 hours, we can use the formula: distance = speed × time.

For the pedestrian: - Speed = 3 km/h - Time = 2 hours

Using the formula, we can calculate the distance traveled by the pedestrian: distance_pedestrian = 3 km/h × 2 hours = 6 km.

For the cyclist: - Speed = 4 × 3 km/h = 12 km/h (since the cyclist's speed is 4 times greater than the pedestrian's speed) - Time = 2 hours

Using the formula, we can calculate the distance traveled by the cyclist: distance_cyclist = 12 km/h × 2 hours = 24 km.

Therefore, after 2 hours, the distance between the cyclist and the pedestrian will be the difference between their respective distances traveled: distance_between = distance_cyclist - distance_pedestrian = 24 km - 6 km = 18 km.

So, the distance between the cyclist and the pedestrian after 2 hours will be 18 kilometers.
