Annette has 2 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 8mph and walks back at a speed of 2mph, how LONG should she speed walking back?

How many times faster does she run than she walks? In other words, if she runs a certain distance in 1 minute, how many minutes would it take her to walk that same amount?

Now that you know that, you can figure out what proportion of the time she spends walking versus running.

Can you take it from there?
