Answer» ONG>Answer: Step-by-step explanation: when the submarine descend 250 m,then the FINAL position is 1000 m so basically ,the submarine travelled all the way up which is 1000 m in 40 minutes. the submarine travelled at a speed of 1000/40 meter/minute , which is 25 meter a minute... the submarine covers 25 meter in a minute. |
