By dividing distance of a moving body with time, we obtain……..
a)speed
b) mass
c)gravity
d) force
If a body moves for 10 seconds with speed of 30 m/s then its covered distance is……..
a) 30 m
b) 3 m
c) 300m
d) 150 m
Calculation:
total time= 10 s total speed=30 m/s
total distance=?
total distance= total speed x total time
total distance= 30 m/s x 10 s= 300 m
