A car travels first half distance between two places with a speed of 40 kmph and the rest half distance with a speed of 60 kmph. The average speed of the car is A. 48 kmph B. 37 kmph C. 44 kmph D. None of these Answer Workspace Report Discuss Answer with explanation Answer: Option A Explanation we know that speed = distance traveled/time taken let the total distance traveled by the car is 2x km. then time taken by it to cover first half is x/60 hour. and for second half is x/40 hour. then average speed= total distance traveled/ total time taken. =2x/[(x/60) + (x/40)] =2x/[5x/120] (on simplification) =48 kmph Workspace
