Given that Alice traveled 30 miles in 3 hours. Initially, the distance traveled is 0 miles.
Take distance on the x-axis and time on the y-axis.
From the given information, the two points on the graph are (0,0) and (30,3).
Mark the points on the graph.
The distance-time graph of a body is a straight line. Join the points by a straight line to get the required graph.
