A circular swimming pool holds 1.22 x 10^6 cubic inches of water. It is being filled at a rate of 1.5 x 10^3 cubic inches per minute. How many hours will it take to fill the swimming pool?

 

The ^ is referring to an exponent.

Answer 1

First the time needed to fill in minutes

 

1.22 x 10⁶ / 1.5 x 10³

0.81333 x 10³

 

Convert to hours

 

0.81333 x 10³ / 60

0.013555 x 10³

13.555

 

The tank shall be full  a little after 13.5 hours.
