5. A train travels 16 miles in
20 minutes. At this rate, how
many minutes will it take to
travel 12 miles?

Answer 1

Answer: 15 minutes

Explanation:

Let's make a proportion

16 miles - 20 minutes

12 miles - х minutes

Hence,

`\displaystyle\\x=(12(20))/(16) \\\\x=(3(4)(4)(5))/(4(4)) \\\\x=3(5)\\\\x=15\ minutes`
