Hello,

Okay, So to get to your answer, -56 in 4 minutes. And it wants to know how much in the first minute. So what I would do is to divide -54 by 4. And your answer would be -14.


Hope this helps

divide total depth by time:

-56 /4 =14

so it is diving at 14 miles per minute

so after the first minute it was at -14 miles
