43. A bug and a housefly are resting at one corner of a cubical room with 3 m long sides. Both of them see a prey located at the diagonally opposite corner of the room at the same time and immediately start running/flying towards it. While the bug has to move on the floor or the walls and cannot fly, there is no such restriction for the housefly. Based on this information, and the assumption that they take up the shortest possible routes, which of the following statements is definitely correct ?

1. The housefly reaches the prey first irrespective of its flying speed.

2. Irrespective of the moving/flying speed, both have to travel a distance of over 5 m.

3. If the bug moves at 3 m/s and the housefly flies at 1 m/s, both of them reach the prey at the same time.

4. With equal flying and moving speeds, the fly will be able to catch the prey and come back to its original position, while the bug will not even be able to reach the original position of the prey (the diagonally opposite corner) in the same time.

Correct Answer :

Irrespective of the moving/flying speed, both have to travel a distance of over 5 m.
