Samantha has 40 minutes to complete both a Math quiz and a spelling quiz. She completes the spelling quiz in 9 minutes. It takes her 3 times as long to complete the Math quiz. How much time does she have left over?

To find the answer,we need to first find the time taken for Math quiz by multiplying 9 by 3:

9×3
=27

We cam then find how many time she leftover:

40-9-27
=4mins

Therefore 4 minutes were leftover.

Hope it helps!

If her spelling quiz was 9 minutes and her math quiz was 3 times as long you find that answer by doing the following math.

9x3=27 minutes (time for her math quiz)

27 minutes + 9 minutes = 36 minutes

40 minutes - 36 minutes = 4 minutes
