Two buses leave towns 1365 kilometers apart at the same time and travel toward each other. One bus travels 17km per hour slower than the other. If they meet in 7 hours, what is the rate of each bus?

Solution

Solution

first bu s^{'} s speed : 89

second bu s^{'} s speed : 106

Solution steps

Translate the problem into an equation:

x \cdot 7 + (x + 17) \cdot 7 = 1365

Solve for

x, x \cdot 7 + (x + 17) \cdot 7 = 1365 : x = 89

Find speed

first bu s^{'} s speed : 89

second bu s^{'} s speed : 106
