**Kim**, Monday, April 30, 2012 at 2:42amT(bike)= 3/4hour= 0.75hour

T(bus)1/4hour=0.25 hour

R(bus)=R(bike)+20

Since D = R*T, then we have the equation

T(bus)*(R(bike)+20)=T(bike)*R(bike)

0.25*R(bike)+ 5 =0.75*R(bike)

Thus, R(bike)=10mph

R(bus)= 10+20= 30mph

D = 10*0.75= 7.5 miles

or D = 30*0.25= 7.5 mies
