Question

A cyclist travels a distance of 1 km in the first hour , 0.5 km in the second hour and 0.3 km in the third hour. Find the average speed of the cyclist in (i) km h-1, (ii) m s-1.​

Answer 1

Answer:

1. 0.6 km/h
2. 0.16 bar m/s

Explanation:

• Total distance = 1.8 km
• Total time = 3 hour
• Average Speed = total distance / total time
• Average Speed = 1.8 / 3
• = 0.6 km/h
• Total distance = 1800 m
• Total time = 10800 sec
• Average Speed = total distance / total time
• Average Speed = 1800 / 10800
• Average Speed = 0.1666666666666666666666666666666666666666666 m/s
