Answer:
43.33
33.33
Step-by-step explanation:
Speed = distance/time
Now, submarine A is presently 1100ft away from sea level and still needs to cover a distance of 200ft below sea level. The total distance it needs to cover is 1100 + 200 = 1300ft
Submarine B is at a distance of 800ft above sea level and still needs to go 200ft below. Total distance needed to be covered is 800 + 200 = 1000ft.
The speed of submarine A = 1300/30 = 43.33ft/min
The speed of submarine B = 1000/30 = 33.33ft/min
Answer:
Submarine A must travel at a rate of StartFraction negative 1100 minus (negative 200) over 30 EndFraction = negative 30 ft/min, and Submarine B must travel at a rate of StartFraction negative 800 minus (negative 200) over 30 EndFraction = negative 20 ft/min.
