Question

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?

Answer 1

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!

Answer 2

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
