Question

Из двух посёлков одновременно навстречу друг другу выехали велосипедист и мотоциклист они встретились через 4 часа каково расстояние между посёлками если известно что скорость велосипедиста 15 км в 1 час а скорость мотоциклиста 40 км в 1 час

Answer 1

Решение:
1)40+15=55(км/час)-скорость сближения.
2)55×4=220(км)-расстояние между поселками.

Answer 2

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously from two different villages and meet each other after 4 hours. We are also given the speed of the cyclist (15 km/h) and the speed of the motorcyclist (40 km/h). We need to find the distance between the two villages.

Solution

To find the distance between the two villages, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by the cyclist and the motorcyclist separately and then find the total distance between the villages.

The distance traveled by the cyclist can be calculated as follows: distance_cyclist = speed_cyclist × time = 15 km/h × 4 hours = 60 km.

The distance traveled by the motorcyclist can be calculated as follows: distance_motorcyclist = speed_motorcyclist × time = 40 km/h × 4 hours = 160 km.

The total distance between the villages is the sum of the distances traveled by the cyclist and the motorcyclist: total_distance = distance_cyclist + distance_motorcyclist = 60 km + 160 km = 220 km.

Therefore, the distance between the two villages is 220 km.

Answer

The distance between the two villages is 220 km.
