Question

Wally takes 45 min to swim 15 laps in the swimming pool. After a while, he grew tired and took 15% more time to complete another 15 laps. Find the time taken by Wally to complete the 15 laps for the second time

Answer 1

Wally took 51.75 minutes to complete another 15 laps after growing tired, which is 15% more time than the initial 45 minutes.

Step-by-step explanation:

Wally initially takes 45 minutes to swim 15 laps. If he takes 15% more time for another 15 laps, we need to calculate the additional time and add it to the original time to find the total time taken for the second set of laps. First, find 15% of 45 minutes:

15% of 45 minutes = 0.15 × 45 = 6.75 minutes.

Now, add this extra time to the initial 45 minutes to find the total time for the second set of laps:

45 minutes + 6.75 minutes = 51.75 minutes.

Therefore, Wally took 51.75 minutes to complete the 15 laps for the second time.
