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?

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

it would be a on edgenuit y

the diagram below is your final answer
