Question

researcher found that the sea level rose 1 5 of a centimeter in 2 3 of a year. At what rate did the sea level rise? A) 2 5 centimeter per year B) 3 5 centimeter per year C) 2 15 centimeter per year D) 3 10 centimeter per year

Answer 1

D)
`(3)/(10)\ cm/year`

Explanation:

Given:

Amount of sea level rose =
`(1)/(5)\ cm`

Number of years =
`(2)/(3)\ years`

we need to find the rate at which sea level rise.

Solution:

Now we know that;

rate at which sea level rise can be calculated by dividing Amount of sea level rose by Number of years.

framing in equation form we get;

rate at which sea level rise =
`((1)/(5))/((2)/(3)) = (1)/(5)*{(3)/(2)= (3)/(10)\ cm/year`

Hence sea level rise at rate of
`(3)/(10)\ cm/year`
