The Ocean floor is at -96m. Tom has reached -15m. If he continues to move at -3m per minute, how far will he be from the ocean floor after 7 minutes?

First, you add -3 to itself 7 times.

- 3 + - 3 + - 3 + - 3 + - 3 + - 3 + - 3 = - 21
Then, add the distance he went to the distance he's already went.

- 21 + - 15 = - 36
Do -96--36 to find how far he is from the ocean floor.

- 96 - - 36 = - 96 + 36 = - 60
So, he is 60m from the ocean floor
