The Nautile, a French submarine, can dive to a depth of 20,000 feet. It takes 20 hours to dive to the maximum depth at the speed of x feet per hour. How fast must the Nautile dive to reach the maximum depth?


Blank Space__________feet per hour

Answer 1

Blank Space needs to be filled with the number of feet per hour that the Nautile must dive to reach the maximum depth. This can be found by dividing the maximum depth (20,000 feet) by the time it takes to reach that depth (20 hours).

So Blank Space should be filled with:

20,000 feet / 20 hours = 1,000 feet per hour

Therefore, the Nautile must dive at a speed of 1,000 feet per hour to reach the maximum depth.
