Question

A race car Travel 100 feet in five seconds at this rate of speed how many feet will the race car travel in a minute?

Answer 1

Convert minute to seconds (1 minute = 60 seconds), set up a proportion, cross multiply, and solve.

Proportion:
`(100 ft)/(5 sec)` =
`(x)/(60 sec)`

Cross multiply: 60 · 100 = 5 · x

Solve (divide both sides by 5): 1200 = x

Answer: 1200 ft
