Question
A superbike takes 84 minutes to cover 112 km. If the
speed of the superbike is decreased by 20 km/h, then find the time taken by the superbike to cover the same distance.Solution
Speed of the superbike = (112/84) x 60 = 80 km/h New speed of the superbike = 80 - 20 = 60 km/h So, required time = (112/60) x 60 = 112 minutes or 1 hour and 52 minutes
