Red Riding Hood drives the 432 miles to Grandmother’s house in 1 hour less than it takes the Wolf to drive the same route. Her average speed is 6 mph faster than the Wolf’s average speed. How fast does Red Riding Hood drive?
R = Red's rate
R-6 = Wolf rate
432/R = 432/(R-6) -1
432(R-6) = 432 R - R(R-6)
Solve for R = 54 m/hr (via Quadratic Formula after simplifying) Wolf = 48 m/hr
