Question

A submarine descends at a rate of 60 feet per minute. How long will it take to descend to a depth of 900 feet. ?

Answer 1

`Formula\ for\ veolocity:\\\\ velocity=(distance)/(time)\\ v=60(feet)/(min)\\ distance=900feet\\\\ velocity*time=distance\ \ |Divide\ by\ velocity\\ time=(distance)/(velocity)\\ time=(900)/(60)=15minute\\\\ \textbf{It\ will\ take\ 15\ minutes.}`
