Question

A top fuel dragster can use as much as 6 gallons in 4 1/2 seconds to travel 1/4 mile.at this rate, how many gallons of fuel will it take for the dragster to go 1 mile

Answer 1

Answer:

24

Step-by-step explanation:

Answer 2

Since the dragster can travel 1/4 of a mile in just 4½ seconds, how long will it take it to travel a whole 1 mile?

well, a whole mile is 4/4 of a mile, 4/4 = 1, since 1/4 of a mile takes 4½ seconds, 4 times that much is just 4½+  4½+  4½+  4½, namely 18 seconds.

so it does a whole mile in 18 seconds, and on each of those 4½ intervals, it burned 6gallons of fuel, namely 4 * 6 gallons.
