Explanation Given: For a five-hundred-miles race Alexander Rossi’s speed was 92 miles per hour more than Ray Harroun’s speed and he took 3.6 hours less time than Harroun. Formula Used: Time = Distance Speed and, solution of the general quadratic equation a x 2 + b x + c = 0 is given by x = − b ± b 2 − 4 a c 2 a Calculation: Consider the speed of Harroun is x miles per hour. Then, the speed of Rossi will be x + 92 miles per hour . Since, distance covered for both is same as 500 miles . Also, it is provided that Rossi took 3.6 hours less than Harroun that can be written as 500 x − 500 x + 92 = 3.72 500 ( x + 92 − x ) x ( x + 92 ) = 3.72 500 × 92 = 3.72 x ( x + 92 ) 500 × 92 3
