The number of boys if the total height of the boys is 26.4 meters and their average height is 1.2 meters the average rate of elevation change in feet per second if a submarine dives 440 feet in 20 seconds

A) Divide the total height by the average height:

26.4 / 1.2 = 22 total boys.

B) Divide total feet by total time:

440 feet / 20 seconds = 22 feet per second.\

Because the submarine is diving the rate would become negative 22 feet per second.

The answer would be 73.6

Step-by-step explanation: We have to 32x2.3 to get 73.6.

Hope this helps!
