Question

Draw Conclusions: A submarine descends from sea level to the entrance of an underwater cave. The elevation of the entrance is -120 feet. The rate of change in the submarine’s elevation is no greater than -12 feet per second. Can the submarine reach the entrance to the cave in less than 10 seconds? Explain.

Answer 1

no greater, so max is -12

in 10 seconds
-12 times 10=-120
-120=-120
it can reach it if it goes max speed
but it says, inless than 10 seconds
it requires at least 10 seconds to reach the cave, so it CANNOT reach it in less than 10 seconds

no
