Solution

The correct option is B $20$ km

Using the information provided in the table, we can plot the graph shown above, taking the time on the $x - a x i s$ and the distance (in km) on the $y - a x i s$ .

From the above graph, we can observe that at $7 : 30 a m$ , the distance traveled is $100 k m$ and at $8 : 00 a m$ , the distance traveled is $120 k m$ .

Therefore, the distance covered during the period $7 : 30$ and $8 : 00$ is $120 - 100 = 20 k m$

Hence, option A is correct.
