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
