Ryan and Janelle are each driving from a different location to meet at Mammoth Lakes. When they each stopped for lunch they called each other on their cell phones. Ryan had traveled

How fast was each person driving?

For each driver, divide the miles they had driven by the amount of time they had been driving. This will give you their speed.

Janelle had been driving at

miles per hour, since miles divided by hours is equal to miles in each hour.

Can you find Ryan's speed?If Janelle originally started

miles from Mammoth Lakes and continues traveling at the same rate (from part (a)), how many more hours will it take her to arrive at her destination? Janelle has

more miles to drive. How long will it take to drive miles at miles per hour?
