Draw the velocity-time graph from the following data :


Time (in hours)



7:00



8:00



9:00



10:00



11:00



12.00



13:00



14:00



Speed (in km/hr)



30



45



60



50



70



50



40



45


Here, we take time on the x-axis and speed on the y-axis.
Let us choose the following scale:
On x-axis: 1 cm = 1 hour
On y-axis: 1 cm= 5 km/hr


Now, let us plot (7:00,30), (8:00,45), (9:00,60), (10:00,50), (11:00,70), (12:00,50), (13:00,40), (14:00,45). These points are joined to get the graph representing the given information as shown in the figure below.


Scale:


On x axis: 1cm = 1 hour


On y-axis: 1 cm = 5 km/hr
