Question

A car traveling at 45 mph is going at 66 feet/second. If a car is traveling at 110 feet/second, then it is going at k mph. What is the value of k?

Answer 1

k=75

Explanation:

to get from 66 feet/second to 45 mph you essentially need to multiply 66 by 45 then divide it by 66.
This can be written as: `66*45/66=45`

therefore `45/66` can by used as our multiplier to convert mph to feet/second.

110 feet/second `*45/66= 75`mph
