Question

A scientist uses a submarine to study ocean life.

She begins at sea level, which is an elevation of 0 feet.
She descends for 32 seconds at a speed of 4.9 feet per second.
She then ascends for 49 seconds at a speed of 1.5 feet per second.

Answer 1

The submarine is -83.3 feet below the surface.

32s*4.9ft/s=156.8

0-156.8=-156.8

49s*1.5ft/s=73.5

-156.8+73.5=-83.3
