a pole's shadow measures 24 ft. and length of shadow cast by vertical meterstick was 40 cm. How long was the pole?
The ratio of the meter stick to its shadow (1m/0.4m) is the same as the ratio of the pole to its shadow (h ft/24 ft):
(1 m)/(0.4 m) = (h ft)/24 ft
Where h = the height of the pole. Cross multiply and solve for h:
(1)*(24)/(0.4) = h
60 feet = h
