Final answer:

To find the hours Rana biked yesterday, divide the total miles biked, m, by her biking speed, r miles per hour. This calculation is based on the relationship between speed, distance, and time commonly taught in middle school mathematics.

Step-by-step explanation:

How Many Hours Did Rana Bike Yesterday?

To determine how many hours Rana biked yesterday after covering m miles, we use the formula for time, which is time = distance / speed. Since Rana bikes at r miles per hour and covered m miles yesterday, the time taken is calculated by dividing m miles by r miles per hour.

Time taken by Rana = m miles / r miles per hour

This formula provides the hours Rana spent biking yesterday. It's a straightforward application of the speed, distance, and time relationship often explored in middle school mathematics classes.
