Question

Solve each word problem using a proportion. Round to the nearest tenth or cent when necessary.

Answer 1

9514 1404 393

Answer:

4 feet

Explanation:

One way to write the proportion is ...

lifeguard/water-slide = lifeguard shadow/water-slide shadow

6/60 = s/40

0.1 = s/40

s = 0.1 × 40 = 4

The shadow of the lifeguard is 4 feet long.
