Solution

Solution

first bu s^{'} s speed : 101

second bu s^{'} s speed : 88

Solution steps

Translate the problem into an equation:

x \cdot 5 + (x - 13) \cdot 5 = 945

Solve for

x, x \cdot 5 + (x - 13) \cdot 5 = 945 : x = 101

Find speed

first bu s^{'} s speed : 101

second bu s^{'} s speed : 88
