Question

I need some help with a Math question. I'm not sure how to work it out. All help appreciated.

If a helicopter at 2000 meters begins to descend at 3 meter per second, how far is the helicopter from the ground after a minute and a half?

Answer 1

since there are 90 seconds in a minute and a half  you multiply 90 by 2 getting 270 then you subtract 270 from 2000 and you get 1730 meters which is your answer hope this helps!
