then walked back home. If she averaged 6 miles per hour riding and 3

miles per hour walking, how far is it from her home to the bicycle shop if

her total travel time was 1 hour?

i tried the chart.

Distance Rate Time

Biking d 6mph t

Walking d 3mph 1-t

Total t

I added those two distances together but did not come up with the answer which is 2. Help. If you could show me a formulaic step by step method of solving this problem this solution should show me how to solve other word problems.
