Problema Solution
if a 5 foot 1 inch woman casts a 3 foot 6 inch shadow, the how tall is a nearby tree that casts a shadow of 17 foot 7 inch
Answer provided by our tutors
1 ft = 12 in
5 ft 1 in = 5*12 + 1 = 61 in
3 ft 6 in = 3*12 + 1 = 37 in
17 ft 7 in = 17*12 + 7 = 211 in
let h = the height of the tree in inches
61 : 37 = h : 211
by solving we find
h = 347.86 in
click here to see the step by step solution of the equation
h = 28 ft 11.86 in
the tree is 28 feet and 11.86 inches tall.
