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

They form at right angles. The reason is the highways meet at right angles is that the United States does something really interesting and well thought out with its highway system.

The even numbers run East and West.
So I-75 runs North and South
I-80 runs East and West.
They will, when they meet, form a right angle. This works for the interstates, but there a system for the intrastates as well.
I wish Canada would do something like that.
