okok

speed=totaldistance /totaltime
per hour=60 min
so for 4 sec it traveled 16m=16/4=4m per hour
for 2sec it travelled 16m=16/2=8min per hour
per hour=60 min
so for 4 sec it traveled 16m=16/4=4m per hour
for 2sec it travelled 16m=16/2=8min per hour
ok?
thank you santhi
welcome

≡formula for finding speed///⌠S=D/T⌡
s-speed
D-distance covered
T-time take to travel
where the object travels 16m in 4s /where the speed is 16/4 = 4 m/s= 14.4km/s
where the another object gravels 16m in 2s /where the speed is 16/2 = 8m/s=28.8km/s
