Lightning travels much faster than thunder, so lightning is seen before thunder is heard. Using inductive reasoning and the graph to the right, if you count 60 s between the lightning and thunder, how far away is the storm?

Answer:
The correct answer is 9 seconds.
Step-by-step explanation:
On your graph, use a ruler and your eye to get the best fitting line.
Then find the time in seconds (45) which is between 40 and 50 on the x-axis.
Go across to the y axis. You will find it is about 9 seconds.
