First of all, we need to figure out how many inches in total, so there are 17 inches per minute, we need to figure out how many per hour, so 60 minutes are in a hour.

Set up the problem like this:

17i x 60m = ?
So 17x60 equals 1020 inches.

Next, we need to find out how many feet are in 1020 inches, there are 12 inches in one foot.

Again, the problem should look something like this:
1020 / 12= ?
So, 1020 / 12= 85 feet.

All we have to do is divide 85 feet by 3 feet because there are 3 feet in a yard.

The problem should look something like this:
85 / 3= ?
85 / 3= 28.33..

Therefore, your answer is 28.3 y/hr.
We learned how to set up problems and to calculate speed and to find out how to get it.

Friendly Reminder: Distance divided by time equals speed.

Have a great afternoon :))
