Question

The submarine dove 836 feet. It today the rate of 22 feet per minute. What was the depth of the submarine after 12 minute,?

Answer 1

So the rate is 836 feet/22 feet per minute.....

so 836/22 = x/12

then you cross multiply..so 836(12)=22x..

then once you simplify you get 456 feet.

I hope that helped (:
