Question

A submarine is descending to examine the seafloor 2,100 feet below the surface. It takes

the submarine 2 hours to make this descent. What was the submarines speed?

Answer 1

1050 feet per hour.

Explanation:

Going down, the speed was r = d/t

r = the speed.

d = distance which is 2100 feet

t = 2 hours.

r = 2100 / 2

r = 1050 feet per hour.
