Hi I am having trouble working out this type of question for my DS. Bond more fourth....here I go:-
At the local fire station they have different lenghts of hose. The shortest is half the length of the middle sized one, and one fifth of the length of the longest one. If I connect all three hoses together I make a hose of 120m long.
a) How long is the shortest hose?
b) How long is the middle hose?
c) How long is the longest hose?
I would be grateful if someone with a better mathematical brain than I could explain this
