Question

From 1950 to 1970,some glaciers in Alaska thinned by an average of 1.7 ft per year.What was the change in glacier thickness during this period?

Answer 1

20 * 1.7 = ?

Answer 2

34.0

Answer 3

-34

Answer 4

To calculate the change in glacier thickness during this period, we need to multiply the average thinning rate by the number of years. In this case, the average thinning rate is given as 1.7 ft per year, and the time period is from 1950 to 1970, which is 20 years.

To calculate the change in glacier thickness, we multiply the thinning rate (1.7 ft/year) by the number of years (20 years):

Change in glacier thickness = Thinning rate × Number of years = 1.7 ft/year × 20 years = 34 ft

Therefore, the change in glacier thickness during this period is 34 feet.
