Question

The graphs show the distances traveled by two people walking at constant rates. Drag to the table the unit rate that matches each graph.

Answer 1

Answer:

The leftmost graph is a 15 mph rate.  Since the biker starts at 0 miles traveled after 0 hours, and the y-value at x=1 hour is 15, you can say that the person biked 15 miles for the hour.

The rightmost graph is a 23 mph rate.  The 'distance' from 2 hours to 3 hours is 1 hour; additionally, the 'distance' from 69 miles to 46 miles is 23 miles, so you can see that in the 1 hour of travel, 23 miles have been biked.
