To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Answer:
Step-by-step explanation:
Minutes is the x axis, and Distance is the y axis.
At 1 minute it looks like Cassie ran much less than 20 yards and Hector ran much further than 20 yards, so Hector started running faster.
Looking at the y axis at 100yards, it looks like Cassie finished at exactly 5 minutes, but Hector only made it to 80 yards. So Cassie won because it was a 100-yrd race.
You can see Hector stopped and rested for 1 minute once he reached 60-yrds. He stopped after 2 minutes.
