Problema Solution
Tom is 5 Ft. 7 in. tall and his shadow is 2.5 feet. a nearby building has a shadow that is 5 ft. tall. How tall is the building in inches.
Answer provided by our tutors
let the building be x inches tall
since 1ft = 12 inches
Tom is 5 ft 7in = 5*12 + 7 = 67 in
Toms shadow is 2.5 ft = 2.5*12 = 40 in
buildings shadow is 5 ft = 5*12 = 60 in
Toms height : Toms shadow = buildings height : buildings shadow
67 : 40 = x : 60
x = 60*67/40
x = 100.5 in
the building is 100.5 in tall.
