Would the proportion be 15/5

If it takes 15 minutes to get to work, then it takes him another 15 minutes to get home. That means he travels 30 minutes each day going to and from work.

**Jerald**, Wednesday, October 16, 2013 at 9:20pmWhat does the statement in parenthesis saying? Do I just make the proportion using 30 minutes/5?

**Ms. Sue**, Wednesday, October 16, 2013 at 9:23pmI assume your question is asking how many minutes he spends going back and forth to work in a week. You can't use a proportion for this problem.

The part in parentheses means he only makes one round trip each day.

**Jerald**, Wednesday, October 16, 2013 at 9:24pmSo I'd multiply 30*5 to get 150

**Ms. Sue**, Wednesday, October 16, 2013 at 9:25pmYes. You're right.

You could use a proportion.

30/1 = x/5

**Ms. Sue**, Wednesday, October 16, 2013 at 9:43pmYep. It comes out the same both ways we work the problem.
