Alright, lets get started.
Glacier moves through the Gasherbrum Mountains of Pakistan at a rate of 4 inches per day.
Means in 1 day, glacier moves distance = 4 inches
In 1 year or say 365 days, glacier moves distance = [tex]365*4 = 1460[/tex] inches
As we know, 39370.1 inches = 1 kilometer
So, 1460 inches = [tex]\frac{1}{1460}*39370.1 = 0.037[/tex] kilometers
It means glacier will move 0.037 kilometers in 1 year. : Answer
As we know, 1 mile = 63360 inches
4 inches movement takes = 1 day
So, 63360 inches movement will take = [tex]\frac{1}{4} *63360 = 15840[/tex] days
Means 43 years 145 days : Answer
Hope it will help :)
