Quantitative Aptitude ( CCS) Time & distance

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 km/hr

71.11 km/hr

We know avg speed = total distance / total time

condition 1 )

time = 160/64 = 2.5

condition 2 )

time = 160 /80 = 2

total time = 2.5 + 2 = 4.5

9/2 hours

=> avg speed = ( 160 + 160) / 4.5 = 71.11 km/hr.
