88 feet in 2 seconds
how many feet in 1 minute?
1 minute is 60 seconds

so, we can write a proportion and solve
feet/ seconds = feet/seconds
88/2 = x / 60
cross multiply
(88 * 60 ) = 2 * x
5280 = 2x
divide both sides by 2
2640 = x

To check:
88/2 =?= 2640 / 60
44 = 44

So the car travels 2640 feet in 60 seconds, or 1 minute.

(btw just in case you wanted to know also, 2640 feet is equal to 0.5 of a mile, that car travels 0.5 miles in 1 minute)

Hope this helps
