Question

Olivia is an athlete. During training this morning, she ran three

laps. It took her 5/6
minute to finish the first lap. The second lap
took her 1/12
more minutes than the first lap. The third lap took her
1/10
less minutes than the second lap. How much time did it take
her to finish the third lap?

Answer 1

Answer: 49/60 mins.

Explanation:

First lap time = 5/6 minute

Second lap time = 11/12 minute

Third lap = ?

To find the 3rd lap mins, we need to find 5 x 6, which is 30. Then, we need to find 1 1/12 more than 30. Then, when we get that answer, we need to find 1 1/10 fewer mins to get the 3rd lap time. If you do it all right, you should end up with 49 mins or 49/60 mins as a fraction (The denominator was changed to 60 to make the problem more realistic and easier) I hoped this helped.
