A man on tour travels first 160 km at 64 km/hr and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:

35.55 km/hr

36 km/hr

71.11 km/hr

71 km/hr

Answer : Option C

Explanation :

Total time taken = $[\frac { 160 } { 64 }$ + $\frac { 160 } { 80 }]$ hrs= $\frac { 9 } { 2 }$ hrs

Average speed =[360* $\frac { 2 } { 9 }]$ km/hr=71.11km/hr
