Solution
28
Explanation:
The time taken is denoted on x-axis and the number of words types are on y-axis. To calculate words types in 30 seconds. We look for the point on the line graph which corresponds 30 on the x-axis and from that point on the graph, draw perpendicular on the y-axis to find the number of words typed. The Answer comes out to be approximately 28 words in 30 seconds.
