Question

A scientist uses a submarine to study ocean life.

She begins at sea level, which is an elevation of 0 feet.
She travels straight down for 68 seconds at a speed of 0.8 feet per second.
She then ascends for 11 seconds at a speed of 3.8 feet per second.

Answer 1

-11.8

Explanation:

68x0.8

11x3.8

11x3.8=41.8

68x0.8=54.4

54.4-41.8=12.6

Now minus add a minus to it and you get -12.6 FT
