Identify the unit rate on the graph 420 36300 240 180 120 60 miles 1 2 3 4 5 6 7 8 number hours

To find the unit rate on the graph, we need to determine the rate at which the number of miles increases per hour.

Going from 0 hours to 1 hour, the number of miles increases from 0 to 420 miles. This is an increase of 420 miles.

Going from 1 hour to 2 hours, the number of miles increases from 420 to 36300 miles. This is an increase of 36300 - 420 = 35880 miles.

The pattern continues for the rest of the points on the graph.

To find the unit rate, we need to divide the increase in miles by the increase in hours for each interval. The unit rate is:

420 miles/1 hour = 420 miles/hour
35880 miles/1 hour = 35880 miles/hour
... (continue for the remaining intervals)

So the unit rate on the graph is 420 miles per hour.
