Ryan and Janelle are driving from different locations to meet at Mammoth Lakes. When they each stopped for lunch, they called each other on their cell phones. Ryan had traveled 245 miles in 3hours. Janelle had driven 260 miles in 4 hours. How fast was each person driving?

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.

is should be y = 5x

correct me if im wrong

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
