Accepted Solution

A:

Answer:a. 3/5b. 6 hours c. 9 hoursStep-by-step explanation:Given: Dave can clean pools at a constant rate of 3/5 pools/hour.this means he cleans 3 pools in 5 hours a.the ratio of number of pools to the number of hours= 3/5b. since, we can clean 3 pools in 5 hours this means he can clean 1 pool in 3/5 hours so, he can clean 10 pools in 10Γ3/5 hours = 2 hours. c. so, for 15 pools it will take 15Γ3/5 = 9 hours
