What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).
So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.
Now you will connect the line M and Z.
Thats it! I hope this helped!! :)

![\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20rate%7D%3D%5Cfrac%7B%5Ctext%7B40%20laps%7D%7D%7B%5Ctext%7B%20hour%7D%7D)
Step-by-step explanation:
Please consider the complete question.
Sebastian swan laps every day in the community swimming pool. He swam 45 minutes each day, 5 days each week, for 12 weeks. In that time, he swam 1800 laps. What was his average rate in laps per hour?
Let us convert time taken into hours as:
![\text{Days}=5\times 12=60](https://tex.z-dn.net/?f=%5Ctext%7BDays%7D%3D5%5Ctimes%2012%3D60)
![\text{Minutes}=60\times 45](https://tex.z-dn.net/?f=%5Ctext%7BMinutes%7D%3D60%5Ctimes%2045)
1 hour = 60 minutes. To convert minutes into hours, we will divide total minutes by 60.
![\text{Hours}=\frac{60\times 45}{60}=45](https://tex.z-dn.net/?f=%5Ctext%7BHours%7D%3D%5Cfrac%7B60%5Ctimes%2045%7D%7B60%7D%3D45)
Now, we will divide 1800 by 45 to find average rate in laps per hour as:
![\text{Average rate}=\frac{\text{1800 laps}}{\text{45 hours}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20rate%7D%3D%5Cfrac%7B%5Ctext%7B1800%20laps%7D%7D%7B%5Ctext%7B45%20hours%7D%7D)
![\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20rate%7D%3D%5Cfrac%7B%5Ctext%7B40%20laps%7D%7D%7B%5Ctext%7B%20hour%7D%7D)
Therefore, Sebastian's average rate is 40 laps per hour.
