From two points at the same time two bicycle pedalists left towards each other. The speed of one of them is 13 km / h, and the speed of the other is 15 km / h. How long will it take for cyclists to meet if the distance between points is 84 km?
The desired unspecified number of hours after which, from the moment of the start of movement, cyclists will find themselves at one point, we define using the conditional variable “Y”.
By the second step, using the conditions of this problem, we compose the following equation: Y = 84 / (13 + 15).
As a result of solving the resulting equation, we have Y = 84/28 = 3 hours.
Answer: cyclists will be at one point after 3 hours.
