Question

If you can swim 15 laps in 5/8 of an hour, how many laps can you swim in 1 hour?

A) 24 laps
B) 20 laps
C) 30 laps
D) 18 laps

Answer 1

To find out how many laps the student can swim in one hour, divide the number of laps (15) by the fraction of the hour (5/8). This results in 15 multiplied by the reciprocal of 5/8, equating to 24 laps in one full hour.

Step-by-step explanation:

If a student can swim 15 laps in 5/8 of an hour, we can calculate the number of laps per hour by dividing the number of laps by the fraction of the hour. The calculation will determine the rate of laps per hour, which can then be multiplied by 1 to find the number of laps in one full hour.

To find the rate of laps per hour:

1. Divide the number of laps (15) by the fraction of the hour (5/8): 15 ÷ (5/8) = 15 ÷ 1 × (8/5) = 15 × (8/5) = 24.
2. Therefore, in one hour, the student can swim 24 laps.

The answer is: A) 24 laps.
