The death of a swimming pool is 8.5 meters what is half of the depth in millimeters

Dollars per hour is $10 and hours per dollar is 6 minutes 15 seconds.

Step-by-step explanation:

Dollars per hour represents how much she earns for each hour of work. Hours per dollar represents how much she works to earn $1.

It is stated that Mariah earns $10 for each hour of work at the movie theater.

This is the "dollars per hour" rate since the base is 1 hour.

This means that she earns 10/60 = $0.16 for every minute she works at the theater. If we divide 1 by this number we find 1/0.16 = 6.25.

This is the minutes she has to work to earn $1. So her hours per dollar rate is 6.25 minutes which is 6 minutes 15 seconds.

I hope this answer helps.
