64.8 km/hr
D=50 m=0.05 km
T=5 min + 5 min=10 min=600 s
S=D/T=0.05/600
D=50 m=0.05 km
T=5 min + 5 min=10 min=600 s
S=D/T=0.05/600

Total distance= 50+50=100m
Time =5 min
Speed = distance/time
Speed= 100/5
Speed= 20m/min
Speed = (20×60) /1000 km/hr
Speed= (2×3)/5
=6/5 =1.2 km/hr
Time =5 min
Speed = distance/time
Speed= 100/5
Speed= 20m/min
Speed = (20×60) /1000 km/hr
Speed= (2×3)/5
=6/5 =1.2 km/hr
