Answer 1

Option D

- 1916 inches

Explanation:

To easily solve this problem, we apply a rule of three

-916 inch ---------------------------------- 3 hours

x inch ---------------------------------- 8 hour

x = 916 inc * (8 hours / 3 hours)

x = 2442.66 inch

The nearest number for this value is option D

(Lets remember we are talking about average values)
