A cyclist travels a distance of1km in the first hour,0.5km in the second hour and0.3km in the third hour. What is the average speed in (1)km/hr(2)m/sec? ?
Step-1 Finding the average speed in km/hr
Distance in one hour =1km
Distance in second hour=0.5km
Distance in third hour =0.3km
We know that,
Average speed inkm/hr
Step-2 Finding the average speed in m/sec
Average speed in m/sec
Therefore, Average speed is0.6km/hr and 0.167m/sec.
Solve the following.
A student covers a distance of 2km in the first hour, 2.5km and 1.5km in the second and the third hour respectively. Find the average speed.
