A taxi goes from City A to City B at an average speed of 84 km/hr. In...
Let's assume the distance between City A and City B is D km.
Average speed = Total distance / Total time
Average speed from City A to City B = 84 km/hr
Average speed from City B to City A = 84 km/hr - 24 km/hr = 60 km/hr
We need to find the average speed for the total journey, which is the average of the speeds from City A to City B and from City B to City A.
Total distance for the journey = Distance from City A to City B + Distance from City B to City A = D + D = 2D km
Total time for the journey = Time from City A to City B + Time from City B to City A
Time from City A to City B = Distance from City A to City B / Average speed from City A to City B = D / 84
Time from City B to City A = Distance from City B to City A / Average speed from City B to City A = D / 60
Total time for the journey = D / 84 + D / 60 = (5D + 7D) / (5 * 12) = 12D / 60 = D / 5
Average speed for the total journey = Total distance / Total time = 2D / (D / 5) = 2D * 5 / D = 10
Therefore, the average speed of the taxi for the total journey is 10 km/hr.
Since none of the given options match the calculated value, there seems to be an error in the question or the answer choices are incorrect.
Average speed = Total distance / Total time
Average speed from City A to City B = 84 km/hr
Average speed from City B to City A = 84 km/hr - 24 km/hr = 60 km/hr
We need to find the average speed for the total journey, which is the average of the speeds from City A to City B and from City B to City A.
Total distance for the journey = Distance from City A to City B + Distance from City B to City A = D + D = 2D km
Total time for the journey = Time from City A to City B + Time from City B to City A
Time from City A to City B = Distance from City A to City B / Average speed from City A to City B = D / 84
Time from City B to City A = Distance from City B to City A / Average speed from City B to City A = D / 60
Total time for the journey = D / 84 + D / 60 = (5D + 7D) / (5 * 12) = 12D / 60 = D / 5
Average speed for the total journey = Total distance / Total time = 2D / (D / 5) = 2D * 5 / D = 10
Therefore, the average speed of the taxi for the total journey is 10 km/hr.

A taxi goes from City A to City B at an average speed of 84 km/hr. In...
Speed of taxi from City A to City B = 84 km/hr
Speed of taxi from City B to City A = 84 - 24 = 60 km/hr
We know that if the distance is same, then the average speed is the harmonic mean of the given speeds.
So,
Required average speed
