A submarine was diving at a rate of 96.4 feet per minute. Which expression shows the submarine’s position in relation to the surface, in feet, after 5 minutes?

Step-by-step explanation:

The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:

d=rt

where

d is the distance traveled (or descended),

r is the rate of travel and

t is the time.

In this problem we are told the rate,r is 96.4 feet per minute. And, we are told the time, t

to calculate for which is 5 minutes.

Substituting these into the formula and calculating gives:

d=90feetmin

t=5min

d=96.4feetx5

d=482feet

each side has a different length.
