two boys on bicycles start toward each other at the same time from two towns 70 km apart. the first travels at 12km/h. what is the speed of the other boy if they meet in 2 1/2 hours?
***
let x=speed of other boy
distance=travel time*speed
..
2.5*12+2.5x=70
30+2.5x=70
2.5x=40
x=16
speed of other boy=16 km/h
