Answer provided by our tutors
let
v1 = 8 mph is the speed of Bill
v2 = 3 mph is the speed of Sam
the distance that Bill rides + the distance that Sam walks = 8.25
let d represent the distance from Sam's house in h hours
For Bill the equation is:
d = 8.25 - v1*h
d = 8.25 - 8h
For Sam the equation is:
d = v2*h
d = 3h
