Question

It take Zoe 2.5 minutes to swim 20 laps around the pool what is Zoe's unit rate

Answer 1

Time taken to swim 20 laps = 2.5 minutes

Hence, time taken to swim 1 lap will be =
`(2.5)/(20)` =0.125 minutes

Or convert it into seconds =
`0.125*60=7.5` seconds

Hence, Zoe's swim rate is 1 lap per 0.125 minutes. Or 1 lap per 7.5 seconds.
