Explanation:
Avrage speed = total distance cover / total time taken
given
total time 4 h
total distance = 0.5 + 0.3 + 1 km(s) = 1.8 km
by putting values
avrage speed = 1.8km / 4
= .9/2
= .45 km/h is avrage speed

Explanation:
Distance travelled in first hour = 1 km
Distance travelled in second hour = 0.5 km
Distance travelled in third hour = 0.3 km
Total time taken = 3 hr
Total distane travelled = 1+0.5+0.3=1.8 km =1800m
1 hour =3600 seconds
3 hour =3600×3=10800 sec.
Average speed in m/s = Distance/ Time
=1800/10800
= 0.167m/s
