I'm like 99.9% sure its 16.8 min, i'm so sorry if its not.
She can do 2.5 push ups in one minute. 16.8x2.5=42 (16.8 represents the minutes)
Answer:
9min
Explanation:
if she does push ups in 2 minutes i counted by 5's
5,10,15,20,25,30,35,40,45
and since she can do 5 every 2 minutes
i did 45÷9 because she did 42 but in fives it goes over
so 45÷9=5
so ur answer is 9
