Mathamatics Investigation

Postby violet04 » Wed Mar 07, 2012 7:43 pm

Hi,
Wonder who can solve the following Bridge Crossing Game? This is part of P3 Mathematics Investigation.

Help all the 5 people to cross the bridge.
It is too dark, so the lantern must be carried when crossing the bridge.
The light in the lantern can only last for 30 minutes.
... Different people walk at different speeds and the bridge can hold only two persons at a time.

Old lady - 12 min
Lady - 8 min
Gentleman with hat - 6 min
Bald Man - 3 min
Man on automated wheelchair - 1 min
