Time = [tex] \frac{distance}{speed} [/tex]
The distance the bag will travel is 5 meters, and the speed it is traveling at is 1 m/s. Plug these into the formula for time.
[tex] \frac{5 m}{1 m/s} [/tex] = 5 s
5/1 = 5 and the m (meters) cancel out, so you are left with s, seconds.
It will take the bag 5 seconds to travel across the floor.
