Question

Мотоциклист проехал путь длиной 336 км со скоростью 42 км/ч. На обратный путь он затратил на 1 час меньше. С какой скоростью ехал мотоциклист на обратном пути? Задача на движение. Заранее спасибо!

Answer 1

Решаем применяя формулу S=v*t.
S=336 км
v=42 км/ч
336:42= 8 ч.(за это время проехал путь 336 км)
на обратный путь затратил 8-1=7 ч.
336:7= 48 км/ч (скорость на обратном пути)
Ответ:48 км/ч

Answer 2

Первый путь он проехал за 336:42=8 часов, тогда обратный путь за 8-1=7 часов , 336:7=48км/ч -V обратного пути

Answer 3

Problem Analysis

We are given that a motorcyclist traveled a distance of 336 km at a speed of 42 km/h. On the return journey, the motorcyclist took 1 hour less to cover the same distance. We need to find the speed at which the motorcyclist traveled on the return journey.

Solution

Let's assume that the motorcyclist traveled at a speed of x km/h on the return journey.

To find the speed, we can use the formula: Speed = Distance / Time.

On the forward journey: - Distance = 336 km - Speed = 42 km/h - Time = Distance / Speed = 336 km / 42 km/h = 8 hours

On the return journey: - Distance = 336 km - Speed = x km/h - Time = Distance / Speed = 336 km / x km/h

We are given that the return journey took 1 hour less than the forward journey. So, the time for the return journey is 8 hours - 1 hour = 7 hours.

Now, we can set up the equation:

336 km / x km/h = 7 hours

To solve for x, we can cross-multiply:

336 km = 7 hours * x km/h

Dividing both sides by 7 hours:

336 km / 7 hours = x km/h

Simplifying:

x = 48 km/h

Therefore, the motorcyclist traveled at a speed of 48 km/h on the return journey.

Answer

The motorcyclist traveled at a speed of 48 km/h on the return journey.
