Answer:
<h3>48 feet</h3>
Step-by-step explanation:
First we need to get the total minutes used by the submarine from 10:57 A.M to 11:03 A.M. The total minutes used within the specified period of time is 6 minutes.
If its depth then changed at a rate of 8 feet per minute, the submarine depth after 6 minutes will be expressed as shown;
8 feet = 1minute
x feet = 6 minutes
cross multiply;
x * 1 = 8 * 6
x = 48 feet
Hence the submarine depth at 11.03AM is 48 feet
The reciprocal should be the number flipped...
in this case..

is the reciprocal.
