Two high speed fairies leave at the same time from a city to go to the same island. The first fairy, the cat travels at 38 mph the second fairy, the bird travels at 23 mph. how many hours will the two furious be 75 miles apart?

Sagot :

Step-by-step explanation:

the speed difference is 38 - 23 = 15 mph.

that is the same as one fairy is standing still, and the other is going 15 mph.

so, how long until 15 mph creates a gap of 75 miles ?

remember, speed = distance / time traveled

so,

15 = 75/x

x = 75/15 = 5 hours

after 5 hours they will be 75 miles apart.
