Question

Jaime's mean speed on her drive home from Washington, DC is 63 mph. If the total trip is 252 miles, how long should she expect thedrive to take? Round your answer to two decimal places, if necessary.

Answer 1

Answer: 4 hours

Given that Jaime's mean speed is 63 mph, we can divide the distance by the mean speed to get how long would she take.

$\frac{252\text{ miles}}{\frac{63\text{ miles}}{\text{hour}}}=252\text{ miles }\times\frac{1\text{ hour}}{63\text{ miles}}=4\text{ hours}$

It would take her 4 hours.
