Question
A cyclist travels from point A to point B at a speed of
12 km/h and returns at a speed of 15 km/h. Calculate the average speed for the entire trip if the distance between A and B is 30 km.Solution
Time taken to travel from A to B = 30 / 12 = 2.5 hours. Time taken to return from B to A = 30 / 15 = 2 hours. Total distance = 30 + 30 = 60 km. Total time = 2.5 + 2 = 4.5 hours. Average speed = Total distance / Total time = 60 / 4.5 = 13.33 km/h (approx). Correct answer: D) 13.33 km/h
