A treasure chest things that are right no less than 20 ft./s. The floor of the ocean is at most at -4200 feet. Will the treasure chest reach the ocean floor in the snow three minutes? Explain

No

Step-by-step explanation:

Number of feets per second of treasure chest = 20ft / s

Depth of ocean floor = - 4200

To know if chest will reach ocean depth in 3 minutes ; use the Relation :

Distance = speed * time

Time = 3 minutes = (3 * 60) = 180 seconds

Depth of chest after 180 seconds :

-20 * 180 = - 3600 feets

Hence, chest can't reach ocean floor in 3 minutes

-4200 feets is deeper than - 3600 feets

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
