Question

Из двух городов,расстояние между которыми равно 52 км,одновременно выехали навстречу друг другу два велосипедиста и встретились через 2 ч после начала движения. Найдите скорость каждого велосипедиста,если известно,что первый велосипедист проезжает за 3 ч на 18 км больше,чем второй за 2 ч. решите пожалуйста как нарисовано на символе :

Answer 1

52:2=26
18*2=36
36-26=10
Ответ:10(км)

Answer 2

Problem Analysis

We are given that two cyclists start simultaneously from two cities that are 52 km apart and meet after 2 hours. We need to find the speed of each cyclist given that the first cyclist covers 18 km more than the second cyclist in 3 hours, while the second cyclist covers the distance in 2 hours.

Solution

Let's assume the speed of the first cyclist is x km/h and the speed of the second cyclist is y km/h.

We can use the formula speed = distance / time to find the speeds of the cyclists.

From the given information, we can write the following equations:

Equation 1: x = (52 - 18) / 3 (The first cyclist covers 18 km more than the second cyclist in 3 hours)

Equation 2: y = 52 / 2 (The second cyclist covers the distance in 2 hours)

Now, let's solve these equations to find the values of x and y.

Calculation

Using Equation 1: x = (52 - 18) / 3 = 34 / 3 = 11.33 km/h

Using Equation 2: y = 52 / 2 = 26 km/h

Therefore, the speed of the first cyclist is 11.33 km/h and the speed of the second cyclist is 26 km/h.

Answer

The speed of the first cyclist is 11.33 km/h and the speed of the second cyclist is 26 km/h.

Note: The speeds are rounded to two decimal places for simplicity.
