Answer:
12 days
Step-by-step explanation:
At the end of the first day he has the distance left to climb = 5,250 feet
He plans to climb the distance each day = 500 feet
Number of days to complete his trip = [tex]\frac{5,250}{500}[/tex]
= 10.5 ≈ 11 days
He has already climbed for one day, so he will finish his trip in 1 + 11 = 12 days.
