Question

Один велосипедист ехал со скоростью 12 километров час и был в пути 4 часа С какой скоростью должен ехать на обратном пути чтобы преодолеть его за 3 часа

Answer 1

На обратном пути ехать со скоростью 16 км в чам

Answer 2

Расстояние будет одинаковое в данном случае а время и скорость разные пусть скорость будет х
тогда
12*4 = х*3
48 = 3х
х = 48 :3
x = 16 км.ч

Answer 3

Problem Analysis

We are given that a cyclist traveled at a speed of 12 kilometers per hour for 4 hours. We need to determine the speed at which the cyclist should travel on the return trip in order to cover the same distance in 3 hours.

Solution

To solve this problem, we can use the formula: speed = distance / time.

Let's calculate the distance traveled by the cyclist on the initial trip: distance = speed * time = 12 km/h * 4 h = 48 km.

Now, we can calculate the speed required for the return trip: speed = distance / time = 48 km / 3 h = 16 km/h.

Therefore, the cyclist should travel at a speed of 16 kilometers per hour on the return trip in order to cover the same distance in 3 hours.

Answer

The cyclist should travel at a speed of 16 kilometers per hour on the return trip in order to cover the same distance in 3 hours.
