Question

Catherine likes to go ice fishing. She has learned from experience that she stays warm about 20 minutes for every undershirt she wears. If she wants to stay out for 120 minutes, how many undershirts should she put on?

Answer 1

She needs to wear 6 undershirts

Answer 2

She need to put on 6 underpants

Explanation:

She has learned from experience that she stays warm about 20 minutes for every undershirt she wears.

Time warmed by 1 undershirt = 20 minutes.

Total time she wants to stay out = 120 minutes

Number of underpants required
`=(120)/(20)=6\texttt{ underpants}`

So she need to put on 6 underpants
