30) Larry wants to complete a marathon in under 6 hours, but he knows he can't run the 26.2 miles the whole way. He'll need to run (r) and walk (w). If he is able to walk at four miles per hour and run at six miles per hour, which system of inequalities shows his total running and walking time?

4w+6r>26.2
w+r<6
w+r<26.2
6w+4r>6
w+r>26.2
4r+6w<6
w+r<26.2
6w+4r>6

Explanation

Using the process of elimination, you can dismiss B, C, and D, right away because the run-walk values are reversed. Answer 1 is the correct choice.
