Pierce swims 10 laps in a pool in 8 minutes. He spent the same amount of time on each lap. How much time did each lap take him?

Each lap took him 48 seconds

Step-by-step explanation:

Pierce swims 10 laps in 8 minutes.

Let the amount of time he spent for each lap = t minutes.

Then, since each lap takes equal time, the total time taken for 10 laps = 10t minutes.

But, it is given that the total time taken for 10 laps = 8 minutes.

Therefore,

10t = 8

Divide both sides by 10.

t = 0.8 minutes or

t = 48 seconds
