Hint: What fraction of the length of the bridge in on the banks?
Answer: 5,600 inches.
We know that 1÷7 + 1÷8 of the total length is on the banks of the river, and 1÷7 + 1÷8 = 15÷56.
So the river width (4,100 inches) is the remaining 41÷56 of the bridge.
41÷56 x length = 4100
length = 4100 x 56÷41
length = 5600

Hint: Say what you see.
Answer: Scrambled eggs.
Billy was on holiday last year on the island of Delzzup.
Delzzup is a really peculiar shape for an island, it's rectangular, 20 miles long and only 15 feet wide, and totally covered in trees!
It has two tiny villages on it Start and End, unfortunately, a fire has begun at Start and is travelling toward End at around 1 mile per hour.
There is also a wind which is blowing towards End at around 2 miles per hour.
Now, Billy, who is at End, has no way of getting off the island, he cannot pass through the fire, he cannot put the fire out and there is no one to help him.
How can he save himself?
Hint: The solution involves lighting a second fire.
The simplest method is to light a new fire about 1 mile from End. This fire will burn toward End (because of the wind) and when it reaches End, it will go out. Billy can then go to End, knowing that the main fire cannot reach him as his smaller fire has already burned all of the trees down.
During the recent BrainBashers cipher convention, a Morse code contest took place. The contest consisted of a Morse code transmission where the spaces between the letters and words were missing. Can you find the ten girl's names?
Luckily, BrainBashers has provided you with a listing of the Morse code characters:
