Question

Велосипедист и мотоциклист выехали одновременно навстречу друг другу из двух посёлков. Велосипедист ехал со средней скоростья 12км/ч, а мотоциклист 40км/ч.Найди среднюю скорость их сближения.

Answer 1

12+40=52 (км/ч) - скорость сближения велосипедиста и мотоциклиста


И в этой задаче есть второй вопрос :

На какое расстояние они сблизятся за 2 часа ?
52*2=104(км)

Answer 2

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously from two different villages and are moving towards each other. The cyclist has an average speed of 12 km/h, while the motorcyclist has an average speed of 40 km/h. We need to find their average closing speed.

Solution

To find the average closing speed, we need to calculate the sum of their speeds. Since they are moving towards each other, their speeds should be added.

The average closing speed can be calculated using the formula:

Average Closing Speed = Sum of the speeds

Let's calculate the average closing speed:

Average Closing Speed = 12 km/h + 40 km/h

Average Closing Speed = 52 km/h

Therefore, the average closing speed of the cyclist and the motorcyclist is 52 km/h.
