Question

A geologist noticed that a land along a fault line moved 24.8 centimeters over the past 175 years . On average, how much did the land move each year? Round to the hundredths place.

Answer 1

On average, the land moved 0,14 cm each year.

Explanation:

To know how much did, on average, the land move, we should divide the total number of cm over the total number of years:

x=24.8 cm/175 years

x=0,1417 cm each year

If we divide years over cm we will get x in years each cm, which is wrong.

Because the problem asks for the answer rounded to the hundredths place:

x= 0,14 cm each year
