Hill on Avenue 1: Rises 3 vertical feet for each horizontal foot
Hill on Avenue 16: Rises 1 vertical foot for every 3 horizontal feet
We can see that the height of hill on avenue 1 rises much more early than that of the hill on avenue 16.
Hence, hill on avenue 1 would be more difficult for Steeve to run up.
E.g. If the horizontal distance to be covered is 3 feet, the hill in avenue 16 will rise by 1 feet, but that in avenue 1 will rise by 3*3 = 9 feet.
