It will take 5 full rotations for Elena's car to travel ten yards
explanation: 10 yards=30 feet, and there are 12 inches in one foot. multiply 30 by 12. once you do that, you get 360. next, divide 360 by the 72 inches in each full rotation. 360/72=5. so the answer is 5 full rotations
X,=-(5±✓25-36) ,/ 2
x={-5±✓-11)/2
x= -5/2 ± i✓11/2
