Question

Maria answered 15 math problems in 30 minutes. How many problems did she solve in 1 minute. 10 points and a brain liest

Answer 1

She solved 0.5. She solved half on 30 meaning it takes her 2 minutes to solve 1. So in a minute it would take her 0.5 because that’s how much she would have done. 0.5 done takes 30 sec. 1 takes 1 min. 1.5 -1min 30sec and 2 -2 min

Answer 2

Maria solved 0.5 (half) of a problem in 1 min

Explanation:

Set up proportion and cross multiply to solve:

15 problems/30 min = x/1 min

x = 0.5
