Question

из села в город выехал мотоциклист со скоростью 53 км/ч, в то же время из города в село навстречу ему выехал велосипедист со скоростью 18 км/ч. Какое расстояние будет между ними через 3 часа, если расстояние от города до села 220 км

Answer 1

1) 53+18=71 км/ч общая скорость
2) 3*71 = 213 км проедут оба за 3 часа
3) 220-213 =7 км будет между ними через 3 ч

Answer 2

Calculation of Distance

To calculate the distance between the motorcyclist and the cyclist after 3 hours, we need to determine the distance each of them has traveled.

The motorcyclist is traveling from the village to the city at a speed of 53 km/h. Therefore, the distance traveled by the motorcyclist after 3 hours is:

Distance_motorcyclist = Speed_motorcyclist * Time = 53 km/h * 3 h = 159 km.

The cyclist is traveling from the city to the village at a speed of 18 km/h. Therefore, the distance traveled by the cyclist after 3 hours is:

Distance_cyclist = Speed_cyclist * Time = 18 km/h * 3 h = 54 km.

Calculation of Distance Between Them

To calculate the distance between the motorcyclist and the cyclist after 3 hours, we subtract the distance traveled by the cyclist from the distance traveled by the motorcyclist:

Distance_between = Distance_motorcyclist - Distance_cyclist = 159 km - 54 km = 105 km.

Therefore, the distance between the motorcyclist and the cyclist after 3 hours will be 105 kilometers.
