If a person standing 5 feet tall casts a shadow 12 feet long, then how long is a tree's shadow if a tree stands 17.5 feet tall?
the ratio of shadow/height is constant, so
12/5 = x/17.5
or, the height and shadow scale the same way, so since 17.5 is 3.5 times 5, the shadow will be 3.5 times 12 feet long.posted by Steve
got me numbers mixed up, sorry
replace 12 with 17.5
