Question

For the problem below, the simple way to get answer would be 10*-12=-120. But how to write it as an Inequality Expression?
---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?
**Write inequality to prove yes or no
