Question

a fault line moved 24.8 centimeters over the past 175 years. On average how much did the land move each year?

Answer 1

0.142 cm/yr

Explanation:

An average is the sum of all the measurements divided by the number of measurements.

If there was a measurement each year, there were 175 measurements, and their sum is 24.8 cm.

Average movement = 24.8/175

Average movement = 0.142 cm/yr

The land moved an average of 0.121 cm each year
