Question

The ocean’s level is currently rising at about 2 mm per year. At this rate, in how many years will sea level be 5 m higher than now? Answer in units of y.

Answer 1

2500 years

Explanation:

First we write 2mm in m usingthe rule of three 2/1000, which is 0.002m, so the amount of meters it raises per year from this point forward is given by the equation :

M=0.002*years

If we want to see how many years it would take we give M the value 5 and solve for 'years':

years=[tex]frac{{M}{0.002}} [\tex] ,where M=5

years=[tex]frac{{5}{0.002}} [\tex]=2500
