The graph shows how many miles Barrett traveled over a 5 hour time frame. The point (1, 50) is on the graph. What is the unit rate for the first hour?
To find the unit rate for the first hour, we need to determine the distance traveled in the first hour. Since the point (1, 50) is on the graph, we can assume that Barrett traveled 50 miles in the first hour.
Therefore, the unit rate for the first hour is 50 miles per hour.
