travel 15 mi on his bicycle. If Paul rides his bike 20 mi/h slower than
Carlos rides his motorbike, find the speed for each bike.

let s = motorbike speed
then
(s-20) = bike speed
;
write a time equation; time =
C's travel time = P's travel time
=
cross multiply
40(s-20) = 15s
;
40s - 800 = 15s

40s - 15s = 800
25s = 800
s =
s = 32 mph is the motorbike
