Answer:
The speed of the mouse relative to the factory floor is 5 m/s.
Explanation:
Given that,
A factory conveyor belt rolls at 3 m/s, 
A mouse sees a piece of cheese directly across the belt and heads straight for the cheese at 4 m/s, 
To find,
The mouse's speed relative to the factory floor.
Solution,
The resultant velocity of the mouse is given by the resultant of two velocities. It is given by :


v = 5 m/s
So, the speed of the mouse relative to the factory floor is 5 m/s.
