After visiting the Titanic,

Question

After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 1800 meters below the surface of the water, and ascend at 50 meters per hour.

Note: under the water is a negative number.

Write an equation to model this situation (use mm for meters and hh for hours). 

Answer 1

m = 50h - 1800

where m is the depth of the submarine in meters

and h is the number of hours since the submarine began its ascent.
