Distance between Gurgaon and Delhi = S km
Time taken to go from Delhi to Gurgaon = S / 60 hours
Time taken to return = S / 40 hours
Total time = S [ 1/40 + 1/60 ] = S/24 hours
Average speed for the entire journey = total distance / total time duration
= 2 S / ( S/24) = 48 kmph
Time taken to go from Delhi to Gurgaon = S / 60 hours
Time taken to return = S / 40 hours
Total time = S [ 1/40 + 1/60 ] = S/24 hours
Average speed for the entire journey = total distance / total time duration
