To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:
10ft______2hs
120ft_____xhs
If the cleaning rate is the same, then the ratios between both are the same:
From this expression, you can determine the time by multiplying both sides of the equal sign by 120
It will take him 24 hours to clear the 120ft driveway.

Because the slant length is the longest length when looking at the Pythagoras theorm
In this case the slant is y, with x and y as the height and base
y²=
Hence y the slant is the sum of the height and and base and will always be larger
