we know that 1 foot = 0.333333 yards and we have to find out how many yards in 480 feet. let x represent how many yards in 480 feet
[tex] \frac{1~foot}{480~feet}~=~ \frac{0.333333}{x} [/tex]
cross multiply the fractions
1x = 159.99984
Divide 1 from both sides we get 159.99984
x = 159.99984 and when we round it we get 160
so 480 feet = 160 yards
