Question

A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours, he is at an altitude of 700 feet.

Answer 1

I would say 75 feet per hour, though I am not 100% sure.

I first found the difference between hours (6-2 = 4) and then found the difference between distance (700 - 400 = 300). I then divided distance by hours and got 75.
