Answer:
have you tries adding them together?
Answer:
1.5 per hour : 1.2 per hour
Step-by-step explanation:
The computation of the ratio is shown below:
For norma, the one pool would be
= 12 pools ÷ 8 hours
= 1.5 per hour
And for albert, the one pool would be
= 9 pools ÷ 7.5 hours
= 1.2 per hour
So the ratio between them is
1.5 per hour : 1.2 per hour
I just added the two numbers and got the number 100.88
The correct answer is 31. I did it incorrectly the first time, but the answer is 31. :-) Thanks Olivia!
