Question

Из двух пунктов находящихся на расстоянии 24км вышли одновременно автомашины и идут в одном направлении. Вторая машина идёт со скоростью 62 км/ч и догоняет первую через 4 часа. Какова скорость 1 автомашины? Заранее спасибо!!!

Answer 1

S=v*t
1)62*4=248(км) - пройдет вторая машина  за 4 часа.
2)248-24=224(км) - пройдет первая машина за 4 часа.
3) 224:4=56(км/ч)
Ответ: 56 км/ч составляет скорость первой машины.

Answer 2

Problem Analysis

We have two cars that start at the same time and are traveling in the same direction. The second car is traveling at a speed of 62 km/h and catches up to the first car after 4 hours. We need to find the speed of the first car.

Solution

Let's assume the speed of the first car is v km/h.

We know that the distance traveled by both cars is the same, which is 24 km.

The time taken by the first car to cover the distance of 24 km is given by: t1 = 24/v (since speed = distance/time)

The time taken by the second car to cover the distance of 24 km is given by: t2 = 4 (as mentioned in the problem)

Since both cars traveled the same distance, we can equate the time taken by both cars: t1 = t2

Substituting the values, we get: 24/v = 4

Simplifying the equation, we find: v = 24/4 = 6 km/h

Therefore, the speed of the first car is 6 km/h.

Answer

The speed of the first car is 6 km/h.
