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 98 seconds at a speed of 1.5 feet per second.
She then travels directly up for 38 seconds at a speed of 3.2 feet per second.

At this point, how many feet is she below sea level?

Answer 1

25.4

Explanation:

you would multiply 98*1.5 then you would multiply 38*3.2 then subtract the answers from each of them (147-121.6) and you would get 25.4
