The table shows the data collected for Dhruv's walking on a road. Time (in minutes) 0 5 10 15 20 25 Distance (in kilometers) 0 0 . 5 1 1 . 25 1 . 50 1 . 75 In what time periods did Dhruv make the most progress?

By observing the data, we get Time interval = 0 - 5 , Distance = 0 . 5 Time interval = 5 - 10 , Distance = 0 . 5 Time interval = 10 - 15 , Distance = 0 . 25 Time interval = 15 - 20 , Distance = 0 . 25 Time interval = 20 - 25 , Distance = 0 . 25 Hence, the most progress is done by Dhruv in the time interval ( 0 to 5 minutes) and ( 5 to 10 minutes)

Draw the graph of the following table. Is it a linear graph? x 3 4 5 6 7 y 12 16 20 24 28

We have, x 3 4 5 6 7 y 12 16 20 24 28 Plotting the points 3 , 12 , 4 , 16 , 5 , 20 , 6 , 24 and 7 , 28 and joining them we get the following graph: Scale on x - axis: 1 cm = 1 unit Scale on y - axis: 1 cm = 4 units Yes, it is a linear graph.
