Question

Из пункта А в одинаковом направлении одновременно выехал авто со скоростью 84 км.ч и мотоцикл со скоростью 52 км .ч .Авто доехав до пункта В повернулся обратно и через 8 часов встретился с мотоциклом .Найдите расстояние между пунктами А и В

Answer 1

Х-время авто от а до в

84х=8*84+52(х+8)
84х=672+52х+416
84х-52х=1088
32х=1088
х=1088/32 =34ч

34*84=2856км

Answer 2

This is a math problem that requires solving a system of equations. I found some web search results that might help you with this problem. Here is a detailed solution based on the first result:

Let x be the distance between points A and B in kilometers, and t be the time in hours that the car took to reach point B. Then we can write the following equations:

- The car's distance equation: 84t = x - The motorcycle's distance equation: 52(t + 8) = x + 84 * 8 - Solving for x and t, we get: x = 336 km and t = 4 hours

Therefore, the distance between points A and B is 336 kilometers.
