10-60.

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 65 miles per hour, since 260 miles divided by 4 hours is equal to 65 miles in each hour.
Can you find Ryan's speed?

Janelle has 315 more miles to drive. How long will it take to drive 315 miles at 65 miles per hour?
