The rate of surging is 1/4 mile in 25 days.
Thus, in 100 days, a 1-mile surge will be complete.
Or, in 100 days, 5280 feet surge.
Since in 1 day, there are 24 hours,
Thus, 1 foot surge = 100*24/5280 = 5/11 hours.
The correct answer will be C.

We know it takes 25 days to surge 1/4 miles.
It means that it takes 25X24 hours to surge 1/4*5280 feet.
How many hours does it take the glacier to cover one foot?
(25*24)/(5280/4)=5/11
The answer is thus (C).
