Question

Пешеход проходит 4км в час, а велосипедист проезжает за это время в 3 раза больше.На сколько километров в час больше проезжает велосипедист, чем проходит пешеход?

Answer 1

1)  4*3=12(км) в час проезжает велосипедист

2)  12-4=8(км)   в час больше проезжает велосипедист

Answer 2

Calculation of Speed

To determine how many kilometers per hour the cyclist travels compared to the pedestrian, we need to compare their speeds.

Given: - The pedestrian walks at a speed of 4 km/h. - The cyclist travels 3 times more than the pedestrian in the same amount of time.

To find the speed of the cyclist, we can multiply the pedestrian's speed by 3.

The cyclist travels at a speed of 12 km/h.

Difference in Speed

To calculate how many kilometers per hour more the cyclist travels compared to the pedestrian, we need to find the difference between their speeds.

The cyclist's speed is 12 km/h, while the pedestrian's speed is 4 km/h.

To find the difference, we subtract the pedestrian's speed from the cyclist's speed.

The cyclist travels 8 kilometers per hour more than the pedestrian.

Therefore, the cyclist travels 8 km/h more than the pedestrian.
