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

Answer:

D) $\frac{3}{10}\ cm/year$

Step-by-step explanation:

Given:

Amount of sea level rose = $\frac{1}{5}\ cm$

Number of years = $\frac{2}{3}\ years$

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 = $\frac{\frac{1}{5}}{\frac{2}{3}} = \frac{1}{5}\times{\frac{3}{2}= \frac{3}{10}\ cm/year$

Hence sea level rise at rate of $\frac{3}{10}\ cm/year$
