Answer:
a. 3/5
b. 6 hours
c. 9 hours
Step-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= 3/5
b. 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 10×3/5 hours = 2 hours.
c. so, for 15 pools it will take 15×3/5 = 9 hours
Answer:
a. 3/5 pools per hour.
b. 6 pools
c. 25 hours
Step-by-step explanation:
Hi, the answers are.
The ratio of the number of pools to the number of hours is already given in the question. Is 3/5 pools per hour.
Ratio = number of pools/ time
b. We have to multiply the ratio by 10 hours.
3/5 pools/hour x 10 hours = 6 pools
c. we have to divide the number of pools (15) by the ratio
15 pools /3/5 pools/hour = 25 hours
