Question

A submarine is at 20 m below the ground level. If it descends at the rate of 13 m/min, how long will it take to reach -2400 m?​

Answer 1

Answer:

183 mins

Step-by-step explanation:

Submarine is 20m below ground level

⇒ Current submarine level = -20 m

Calculate distance:

level to reach = -2400 m

Distance needed to travel = 2400 - 20 = 2380 m

Calculate time needed:

Distance = 2380m

Speed = 13 m/min

Time needed = Distance ÷ Speed

Time needed = 2380 ÷ 13 = 183 mins
