How many minutes after 11 AM is it when the car overtakes the bicycle? ----- Bike DATA: rate = 16 mph ; time = x hrs ; distance = 16x miles --- Car DATA: rate = 45 mph ; time = x-3 hrs ; distance = 45x-135 miles ----- Equation: distance = distance 16x = 45x -135 29x = 135 x = 4.66 hrs x-3 = 1.66 hrs = 99.31 minutes ==================================== Cheers, Stan H. ==================

Quadratic_Equations/556842: Find the x- and y-intercepts.
