Question 1005717: If a 9-foot tall adult elephant casts an 18-foot shadow, how long is the shadow of the 6-foot zookeeper? Use a proportion to set up and solve an equation. Round your answer to the nearest tenth of a foot if necessary.

The proportion you want is
9 feet / 18 feet shadow = 6 feet / x feet shadow
or 9%2F18+=+6%2Fx
Now cross-multiply and get
9x = 108 and
x = 12 feet
