Question

СРОЧНО Одновременно навстречу друг другу выехали два велосипедиста, и через 0,6 ч они встретились. Найдите первоначальное расстояние между велосипедистами, если их скорости равны 11 и 14 км\ч

Answer 1

1) 11*0.6=6.6(км) проехал один велосепедист, 2) 14*0.6=8.4(км) проехал другой велосипедом, 3) 6.6+8.4=15(км) Ответ:15 километров первоначальное расстояние между велосепедистами

Answer 2

Problem Analysis

We have two cyclists who start simultaneously and ride towards each other. After 0.6 hours, they meet. The speeds of the two cyclists are given as 11 km/h and 14 km/h. We need to find the initial distance between the cyclists.

Solution

To find the initial distance between the cyclists, we can use the formula: distance = speed × time.

Let's assume the initial distance between the cyclists is d kilometers.

The first cyclist travels at a speed of 11 km/h for 0.6 hours, covering a distance of 11 × 0.6 = 6.6 km.

The second cyclist travels at a speed of 14 km/h for 0.6 hours, covering a distance of 14 × 0.6 = 8.4 km.

Since they meet after 0.6 hours, the total distance covered by both cyclists is equal to the initial distance between them.

Therefore, we can write the equation: 6.6 km + 8.4 km = d km.

Simplifying the equation, we find that the initial distance between the cyclists is 15 km.

Answer

The initial distance between the two cyclists is 15 km.

Explanation

When the two cyclists start simultaneously and ride towards each other, they meet after 0.6 hours. The first cyclist travels at a speed of 11 km/h for 0.6 hours, covering a distance of 6.6 km. The second cyclist travels at a speed of 14 km/h for 0.6 hours, covering a distance of 8.4 km. The total distance covered by both cyclists is equal to the initial distance between them, which is 15 km.
