Atreasure chest sinks at a rate no less than 20 feet er second. the floor of the icean is at most at -4,200 feet. will the tresure chest reach the ocean floor in less than 3 minutes? explain.

No.

Step-by-step explanation:

Given: A treasure chest sinks at a rate no less than 20 feet per second.

Speed = -20 feet per second.

The depth of ocean = -4200 feet

Since 1 minute = 60 seconds

Therefore 3 minutes=180 seconds

The depth D reached by treasure chest in 3 minutes is given by :-

Clearly -4200<-3600

Therefore, the treasure chest can not reach the ocean floor in less than 3 minutes.
