a treasure 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.

Respuesta :

Answer: 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=[tex]3\times60=[/tex]180 seconds

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

[tex]D=Speed\times time\\\Rightarrow\ D=-20\times180\\\Rightarrow\ D=-3600\ feet[/tex]

Clearly -4200<-3600

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