Question

Two buses leave towns 555mi

 apart at the same time and travel toward each other. One bus travels 11

 /mih

 faster than the other. If they meet in 5

 hours, what is the rate of each bus? 

rate of the faster bus?

rate of the slower bus?

Answer 1

d = rt

The busses are travelling a total of 555 miles.

555 = 5r + 5(r + 11)

555 = 5r + 5r + 55

10r = 500

r = 50

50 + 11 = 61

faster bus 61 mph

slower bus 50 mph
