underinsured driver.
2. A car traveling at an average rate of 60 miles per hour will drive 270 miles in 4 hours.
3. A car traveling on asphalt makes a sudden stop. The drag factor of the road is 0.7 and the brakes are
operating at 90% efficiency. If the car leaves 4 distinct skid marks that are 60 feet long, then the car was
traveling about 37 miles per hour.
4. In the box-and-whisker plot below, 50% of the data is between 30 and 70.

7. Victor found 5 cars online that he is going to go and see. The prices of the cars are: $5,000, $4,500, $5,500,

If the advertisement she wants to place will be 7 lines, how much will the paper charge her?
