Question

Пешеход за 2 часа прошел 8 км а велосипедист за то же время проехал 20 км. На сколько скорость велосипедиста больше скорости пешехода?

Answer 1

1) 8:2=4(км/час)-скорость пешехода
2)20:2=10(км/час)-скорость велосипедиста
3)10-4=6(км/час)
Ответ: На 6 км/час скорость велосипеда больше, чем скорость пешехода.

Answer 2

20:2=10км/ч - скорость велосипедиста
8:2=4км/ч- скорость пешехода
10-4=6км/ч- на 6 Км/ч скорость велосипедиста больше скорости пешехода

Answer 3

Calculation of Speed

To determine the difference in speed between the pedestrian and the cyclist, we can use the formula:

Speed = Distance / Time

Given that the pedestrian walked 8 km in 2 hours and the cyclist traveled 20 km in the same amount of time, we can calculate their respective speeds.

The speed of the pedestrian is:

Speed of Pedestrian = Distance / Time = 8 km / 2 hours = 4 km/h The speed of the cyclist is:

Speed of Cyclist = Distance / Time = 20 km / 2 hours = 10 km/h

Difference in Speed

To find the difference in speed between the cyclist and the pedestrian, we subtract the speed of the pedestrian from the speed of the cyclist:

Difference in Speed = Speed of Cyclist - Speed of Pedestrian = 10 km/h - 4 km/h = 6 km/h

Therefore, the speed of the cyclist is 6 km/h faster than the speed of the pedestrian.
