Ram covered 60 km in a bus in 50 min. after deboarding the bus, he took rest for 5 min. There after he took a taxi to his home 30 km away and reached in 20 min.
CONCEPT:
Basic concept of time speed and distance.
FORMULA USED:
Average speed = Total distance/Total time taken
CALCULATION:
Total distance = 60 + 30 = 90 km
Total time taken = 50 + 5 + 20 = 75 min = 5/4 hr
Hence,
Average speed = 90/(5/4) = 72 km/h
