Question: A man on tour travels first 180 km at 96 km/hr and the next 180 km at 80 km/hr. The average speed for the first 360 km of the tour is:

Solution:
Total time taken = (180/96) + (180/80)
= (900 + 1080)/480
= 1980/480
= 99/24

Average speed = 360/(99/24) km/hr.
= (360 × 24)/99
= 960/11 km/hr.
