Amotor scooter travels 20 mi in the same time that a bicycle covers 8 mi. if the rate of the scooter is 4 mph more than twice the rate of the bicycle, find both rates.

The scooter is 20 miles per hour and the bicycle is 8 miles per hour. Because twice the rate of the bicycle is sixteen miles then the scooter minus 16 is four as in the four miles per hour mentioned above, so its only one hour then we divide 20 and 8 both seperatly by one and those are your answers
