As a unit rate, swimming 16 laps in 1 hour is
a. 32 laps per 2 hours
b. 1 lap per 4 minutes
G. 16 laps per hour
d. 8 laps per 30 minutes

The correct answer is D., 8 laps per 30 minutes.

Step-by-step explanation:

We can evaluate by making a ratio table:

Our laps are directly proportional to the time spent completing these laps. I will be measuring time in minutes, rather than hours.

laps: minutes

16: 60  *Simplify

8:30

This is also a logical answer statement as 1/2 of 16 is 8, and 1/2 of an hour (60 minutes) is 30 minutes. Therefore, you're completing 8 laps every 30 minutes.

a² + b²= c²

24² + 7² = c²

c= 25

d
