Question 389156: I need help finding another example about finding distance using a number line.
This is the example my teacher gave:
Michael sees mile marker 237 when he enters the highway and mile marker 159 when he exits, how far did he travel? He travelled 78 miles.
We are not allowed to use the example of mile markers.

How about this: Michael sees a sign that reads "Town A: 150 miles" (ie the distance he is from Town A is 150 miles) and a few hours later he comes upon another sign that reads "Town A: 72 miles". How far has he traveled?


Simply subtract the two figures to get 150-72 = 78. So he has traveled 78 miles. Of course, you can change the numbers to make the distance a different number. For instance, the two numbers could be 200 and 143 giving you a distance of 200-143=57 miles.
