The new naval math


My son had an interesting math problem on his homework tonight:

A submarine descended -15 km per minute to the ocean floor. It took 48 minutes to get there. How deep was the ocean floor?

That’s an amazing submarine that can move backwards in time at such a high rate of speed (-720 KPH) under the water, but we’ll never know the depth until we know the angle of descent.
