Question

After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 1500 meters below the surface of the water and ascend at 37 meters per hour.Note: under the water is a negative number.Write an equation to model this situation (use m for meters and h for hours)

Answer 1

Answer:

$m=37h-1500$.

Step-by-step explanation:

Let m represent meters and h represent hours.

We have been given that Captain Brain and Mr. Pinky start 1500 meters below the surface of the water and ascend at 37 meters per hour.

Since the submarine ascends at a rate of 37 meters per hour, so elevation of submarine after h hours would be $37h$.

Since the elevation under water surface is negative, so 1500 meters below the surface of water would be $-1500$.    

The final elevation in meters of submarine after h hours would be initial elevation plus change in elevation after h hours that is $m=37h-1500$.

Therefore, the equation $m=37h-1500$. represents the given scenario.
