The distance from the initial depth to the maximum depth is:
abs (-200- (-25))= 175 m (distance is always >=0, so we have to take the abs).
175 m* (1 sec/ 2.5m)= 70 sec.
It would take the submarine 70 seconds to reach its maximum depth.
Hope this helps~
The first one is BC
The second one is AB
Because it's a positive number that can be gained by multiplying two smaller positive numbers.
I am pretty sure it is 30. Hope it helps!!
