Question

A cyclist travel a distance of 1km in the first hour and0.5km in the second hour and 0.3km in the third hour find average speed in meters per second

Answer 1

1st hour= 1 km= 1000m
2nd hour= 0.5 km= 500 m
3rd hour= 0.3km= 300 m
average=1000+500+300/3
             =1800/3
average=600m/s

Answer 2

A cyclist travel a distance of

• 1km in the first hour
• 0.5km in the second hour
• 0.3km in the third hour

Avg. Speed

= Total Distance / Total time

= (1 km + 0.5 km + 0.3 km) / 3 s

= (1000 + 500 + 300) m / 3 s

= 1800 / 3

= 600 m/s
