Answer:
Submarine A needs to travel at 30 feet per minute and the Submarine B at a lower speed, 20 feet per minute.
Step-by-step explanation:
This is the information given to solve the question:
Submarine A position = - 1,100 feet
Submarine B position = - 800 feet
New position for Submarine A and B = - 200 feet
Duration of the travel = 30 minutes
Distance that Submarine A need to travel = - 200 + 1,100 = 900 feet
Distance that Submarine B need to travel = - 200 + 800 = 600 feet
For calculating the speed, we do this new calculation:
Speed Submarine A = Distance that Submarine A need to travel/Duration of the travel
Speed Submarine A = 900 feet/30 minutes
Speed Submarine A = 30 feet/minute (Dividing by 30)
Speed Submarine B = 600 feet/30 minutes
Speed Submarine B = 20 feet/minute (Dividing by 30)
Submarine A needs to travel at 30 feet per minute and the Submarine B at a lower speed, 20 feet per minute.
