Kian is driving 48 miles per hour and is starting to merge onto the highway; therefore, he must increase his speed. He gradually accelerates at a rate of 7 miles per hour for several seconds. a. Substitute the initial velocity and constant acceleration into the formula to write an equation to represent the distance Kian travels. b. Use the Quadratic Formula to determine the roots of the equation. What do the roots represent in the context of the problem situation? Explain your reasoning.
