Answer: Ryan drove at 81.67 miles per hour.

Janelle drove at 65 miles per hour.

Step-by-step explanation:

The formula for determining speed is expressed as

Speed = distance/time

When they each stopped for lunch, they called each other on their cell phones. Ryan had traveled 245 miles in 3hours. This means that the speed at which Ryan is driving is

245/3 = 81.67 miles per hour.

Janelle had driven 260 miles in 4 hours. This means that the speed at which Janelle is driving is

260/4 = 65 miles per hour.
