A question on a test asks students to find the speed at which a car travels. The graphs shows a proportional relationship between the distance traveled in miles and time in hours. Anna incorrectly says the speed of the car is 1/62 miles per hour. What is the speed of the car? What error might Anna have made? The speed of the car is 62 miles per hour. What error might Anna have made? A. She used change in y coordinates/change in x coordinates to find a unit rate, not change in x coordinates/change in y coordinates
B. She used change in x coordinates/ change in y coordinates to find a unit rate, not change in y coordinates/ change in x coordinates
