Question 372130: Hello
Could you please answer this question
I have tried to answer it but all i get is 21m and it says in the question that it is not 21m
Thanks
A spider and a fly are in the same room. The spider is hungry and the fly is asleep. The room is 15 m long, 6 m wide and 6 m high. The spider is on an end wall, 0.5 m from the ceiling and halfway between the side walls. The fly is on the other end wall, 0.5 m from the floor and halfway between the side walls. The spider wants to reach the fly but must crawl on the walls, ceiling and floor to get to its prey. What is the shortest route the spider might take? (Hint: The answer is not 21 m.)

You can put this solution on YOUR website! He crawls 0.5 m to the ceiling, 15 m across it, then 5.5 m down the other wall.
The sum is 21 meters.
----------
Any other route will be more than 21 meters.
