Question 942209: A small dog walks 1/5 mile per hour. How long will it take her to walk 2 miles? Draw a picture.
I drew a rectangle and divided it in fifths and divide again in half to represent two miles. My answer was 10 hrs.

You can put this solution on YOUR website!
This is a ratio:
distance [1] / time [1] = distance[2] / time[2]
+%28+1%2F5%29+%2F+1+=+2+%2F+t+
Multiply both sides by +5t+
+t+=+10+ hrs
-----------------
You could draw rectangles with heights
+1%2F5+ and +2+ to show miles
and
rectangles with heights +1+ and
+10+ to show times ( on a different scale )
