He made a computation error when he added 10.35+7.6
The average number of hours can be calculated using the following rule:
average number of hours = total number of hours / total number of weeks
total number of hours = 36 3/8 + 41 1/4 + 40 1/2 + 38 3/8 = 313/2 hours
total number of weeks = 4 weeks
Average number of hours per week = (313/2) / (4) = 39 1/8 hour
Based on the above calculations, the correct answer is:
C. 39 1/8 hour
Based on the calculations, the unit rate in feet per minute for this walking pace is equal to 250 feet per minute.
<h3>How to calculate the unit rate?</h3>
A unit rate refers to a measurement of a quantity which is calculated as a ratio of one parameter to another.
This ultimately implies that, we would divide the distance covered in feet by the time taken to cover this distance as follows:
Unit rate = distance/time
Unit rate = 3750/15
Unit rate = 250 feet per minute.
