1) index cards have a ratio of 5: 3, where 5 represents length and 3 represents width. if we want to cut a piece of poster board to make a blown- up example with a length of 20 inches, how long should we make the width?
2)you are driving in a zone where the posted speed limit is 55 mph. your speedometer reads 50 mph. are you speeding? if so, by how much?
3) you have just changed your factory tires to some larger tires. the circumference of the factory tire is 160 inches and the circumference of the larger tire is 192 inches. if you did not adjust your speedometer for the new tires, what is your actual speed if the speedometer reads 55 mph?
4)the factory installed tires on your truck have a circumference of 104 inches. you replace your tires with new ones that have a circumference of 113 inches. if you then drive on the interstate and your speedometer indicates 65 mph, how fast are you actually travelling?
