Aman covers 60% of distance in 1 day 6 hr and remaining 40% distance in 20 hr Formula used/Concept Used: Speed = Distance/time Average speed = (Total distance)/Total time Calculation: 1 day 6 hr = 30 hr As we know that to calculate the average speed we need total distance and total time ∴ Average speed = [1200/(30 + 20)] = 24 km/hr ∴ The average speed of Aman is 24 km/hr |
