Question

Mia and Liam live in the same apartment and are planning a trip. They are going to take separate cars. Mia drives 15 min at 45 mph, where Liam drives 22 miles at 30 mph. How much longer does it take Liam than Mia?

Answer 1

The problem is asking to compare the times. We already know Mia's time, 15 minutes. Since Liam driving 22 miles at 30mph, the time it takes Liam is time=distance/speed, so t=22/30=0.733 hr x 60= 44 minutes.

It will take Liam 44-15=29 minutes longer than Mia.
