A motorcycle 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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
