Question

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

Answer 1

Answer: 0.141 cm each year

Explanation:

We can solve this by a Rule of three:

If

24.8 cm ---- 175 years

? ----- 1 year

Then:

`?=((24.8 cm)(1 year))/(175 years)`

`?=0.141 cm` This means the land moved on average 0.141 cm per year
