Answer:
considering that Columbus arrived in America in 1492 then is 15.81 m wider.
Explanation:
If Columbus arrived in America in 1492, and now we are in 2019, the difference is 527 years.
If we know that in one year the ocean is getting 3 cm wider, so by rule of three:
1 year = 3 cm
527 years = x X = (3 x 527) /1 = 1581 cm
If we consider 1 m = 100 cm
x = 1581 cm
x = (1581 x 1) /100 = 15.81 meters wider
