along west
dist is 30m
speed is 2m/s
speed =dist/time
time=dist /speed=30/2
=15second
along north
dist is 40m
speed is 4m/s
time =dist/speed
=40/4
=10s
average speed=total dist / total time
=30+40/15+10
=70/25
=2.8m/s
dist is 30m
speed is 2m/s
speed =dist/time
time=dist /speed=30/2
=15second
along north
dist is 40m
speed is 4m/s
time =dist/speed
=40/4
=10s
average speed=total dist / total time
=30+40/15+10
=70/25
=2.8m/s
