A submarine cruised below the surface of the water. During a training exercise, it made 6 dives, each time descending 35 feet more. Then it rose 122 feet. What is the change in the submarine’s position?

68 feet

Step-by-step explanation:

A submarine cruised  below the surface of the water

During training exercise, each time descending= 45 feet

Number of dives= 4

Total distance he descended= 45×4 feet

Total distance he descended= 180 feet

Then, it rose by= 112 feet

Now , the distance he is at below the surface if water= 180- 112

The distance he is at below the surface if water= 68 feet

Now, he is at 68 feet below the surface of the Earth

Hence, the correct answer is 68 feet

Step-by-step explanation:

true
