Two buses leave a station at the same time and travel in opposite directions. One bus travels 13 mph faster than the other. If the two buses are 666 miles apart after 6 hours, what is the rate of each bus?

Solution

Solution

first bu s^{'} s speed : 62

second bu s^{'} s speed : 49

Solution steps

Translate the problem into an equation:

x \cdot 6 + (x - 13) \cdot 6 = 666

Solve for

x, x \cdot 6 + (x - 13) \cdot 6 = 666 : x = 62

Find speed

first bu s^{'} s speed : 62

second bu s^{'} s speed : 49
