Question

Расстояние между двумя пунктами ровно 54 км. Из этих пунктов одновременно навстречу друг другу выехали два велосипедиста. через 2 ч они встретились. До встречи расстояние, пройденное вторым велосипедистом, оказалось в 1,25 раза больше, чем расстояние, пройденное вторым велосипедистом.Найдите скорость первого велосипедиста. Найдите скорость второго велосипедиста.

Answer 1

х -расстояние пройденное вторым велосипедистом

1,25х - растояние пройденное первым велосипедистом

х + 1,25х = 54

2,25х = 54

х = 54 : 2,25

х = 24 км  - расстояние пройденное вторым велосипедистом

24 : 2 = 12 км/час- скорость второго велосипедиста

24 * 1,25 = 30 км растояние пройденное первым велосипедистом

30 : 2 = 15 км/час скорость первого велосипедиста

Answer 2

54 делим на 2 = 27 ...Ну Моими словами Будет Так не знаю как решение записать!! у мамы спросишь..))). 1-Велосипидист....28,25 Км. 2-Велосепедист 27 км! 25,75....

Answer 3

Problem Analysis

We have two cyclists who start simultaneously from two points and meet after 2 hours. The distance between the points is 54 km. The second cyclist covers 1.25 times the distance covered by the first cyclist. We need to find the speeds of both cyclists.

Solution

Let's assume the speed of the first cyclist is x km/h. Since the second cyclist covers 1.25 times the distance covered by the first cyclist, the speed of the second cyclist will be 1.25x km/h.

We can use the formula distance = speed × time to find the distances covered by both cyclists.

The distance covered by the first cyclist in 2 hours is 2x km, and the distance covered by the second cyclist in 2 hours is 2(1.25x) = 2.5x km.

According to the problem, the sum of the distances covered by both cyclists is equal to the total distance between the points, which is 54 km.

So, we can write the equation 2x + 2.5x = 54 and solve it to find the value of x.

Calculation

Simplifying the equation 2x + 2.5x = 54: - 4.5x = 54 - Dividing both sides by 4.5: x = 12

Therefore, the speed of the first cyclist is 12 km/h.

The speed of the second cyclist is 1.25 times the speed of the first cyclist, which is 1.25 × 12 = 15 km/h.

Answer

The speed of the first cyclist is 12 km/h, and the speed of the second cyclist is 15 km/h.
