Question

Велосипедист и мотоциклист выехали одновременно из одного пункта в другом направлении скорость мотоциклиста 40 километров час а велосипедиста 12 километров час Какова скорость удаления друг от друга через сколько часов расстояние между ними будет 56 км

Answer 1

40-12 = 28 км/ч - скорость удаления.
56:28 = 2 ч - через такое время расстояние будет 56 км.

Answer 2

1)40-12=28(км/ч)
2)56÷28=2 (ч.)

Answer 3

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously from the same point, but in opposite directions. The motorcyclist has a speed of 40 km/h, while the cyclist has a speed of 12 km/h. We need to find the speed at which they are moving away from each other and the time it takes for the distance between them to be 56 km.

Solution

To find the speed at which they are moving away from each other, we can add their individual speeds together. The speed at which they are moving away from each other is the sum of their speeds, which is 40 km/h + 12 km/h = 52 km/h.

To find the time it takes for the distance between them to be 56 km, we can divide the distance by their combined speed. The time is equal to the distance divided by the speed, which is 56 km / 52 km/h = 1.08 hours.

Therefore, the speed at which they are moving away from each other is 52 km/h, and it will take 1.08 hours for the distance between them to be 56 km.

Answer

The speed at which the cyclist and motorcyclist are moving away from each other is 52 km/h, and it will take 1.08 hours for the distance between them to be 56 km.
