Carlos can drive 4 times as fast as Raul can ride his bicycleit takes Raul 3 hours longer than Carlos to travel 88 mileshow fast can Raul ride his bicycle?

Answer 1

C=4R

rate of speed times time traveled = distance traveled

R(3+t) = Ct = 88

R(3+t) = 88

Ct =4Rt = 88

4Rt = 88

Rt = 88/4 = 22

3R + Rt = 88

3R +22 = 88

3R = 66

R = 22 mph = Raul's bicycle speed

C =4R = 4(22) = 88 mph = Carlos' driving speed

in one hour Carlos drives 88 miles

in 1+3 =4 hours, Raul bikes 4x22 = 88 miles
