7. A man is riding a bike at a uniform speed of 60 km per hour. Plot a distance-time graph to show the relationship between distance and time. Is it a linear graph?
To plot a distance-time graph, we need to record the distance travelled by the man on the bike at different time intervals. For example, we can use the following table:
Time (hours) Distance (km)
0 0
0.5 30
1. 60
1.5 90
2 120
The distance-time graph can be drawn by plotting the points (time, distance) on a graph paper and joining them with a straight line.
The graph is a linear graph because the distance travelled by the man is directly proportional to the time elapsed. The slope of the graph is equal to the speed of the man, which is constant at 60 km per hour. This means that the man covers the same distance in every unit of time
