A science teacher tells her class that their final project requires students to measure a specific variable anddetermine the velocity of a car with no more than 2.5% error. Jennifer and Johnny work hard and decide thevelocity of the car is 34.87 m/s. The teacher informs them that the actual velocity is 34.15 m/s. Will Jennifer andJohnny pass their final project?
