Question

The Cortez family is traveling from Miami to Washington, D.C. They plan to average 55 miles per hour on their trip.

About how many drive hours will it take the Cortez family to make the trip?

Answer 1

Explanation:

Miami is approximately 1,054 mi away from Washington DC. assuming the Cortez family is driving in a straight line the time they will be on the road is

`let \: h = hrs`

`1054mi / (55mi)/(h ) \\ (1054mi)/(1) * (h)/(55mi) \\ = (1054mi(h))/(55mi)`

The miles unit, mi cancels and leaves us with hours, h

`(1054 \: h)/(55) \: \: \: \: is \: approx. \: \: \: \: 19.16 \: \: hrs`
