Q15. [+2, -0.25]Reasoning
If a car travels from city A to city B at an average speed of 50 km/h and returns at an average speed of 60 km/h, what is the average speed of the car for the entire trip?
A. 50 km/h
B. 54.55 km/h
C. 55 km/h
D. 60 km/h
Correct Answer: B The average speed is calculated using the formula total distance / total time. Let the distance between city A and city B be d. The time taken to travel from A to B is d / 50, and the time taken to travel from B to A is d / 60. The total time is d / 50 + d / 60, which simplifies to (6d + 5d) / 300 = 11d / 300. The average speed is 2d / (11d / 300) = 600 / 11 = 54.55 km/h.
