Question
Andy takes 50 min to swim 15 laps in the swimming pool.After a while, he grew tired and took 18% more time to complete another 15 laps.Find the time taken by Andy to complete the 15 laps for the second time.
Solution
First, we need to find out how much more time Andy took to complete the 15 laps when he was tired. We know that he took 18% more time, so we calculate 18% of the original time, which is 50 minutes.
18% of 50 minutes = 0.18 * 50 = 9 minutes
So, Andy took 9 minutes more when he was tired.
Now, to find the total time taken by Andy to complete the 15 laps for the second time, we add this extra time to the original time.
50 minutes (original time) + 9 minutes (extra time) = 59 minutes
So, Andy took 59 minutes to complete the 15 laps for the second time.
