Question

I need help with this math problem

Answer 1

4 hours

Because 12 times by 3 is 36 so you times 1 hr and 20 mins by 3

1 hr 20+1 hr 20+ 1hr 20 = 4 hrs

Answer 2

She did 12 questions, and needs to do 36.

36 / 12 = 3, so it will take 3 times as long.

1 hour 20 minutes times 3 = 4 hours.

It will take her 4 hours.
