Entry Form
A cyclist rides from one town to another.
On the first day she covers one eighth of the total distance.
The next day she covers one quarter of what is left.
The following day she covers two fifths of the remainder
and on the fourth day half of the remaining distance.
The cyclist now has 14 miles left.
How far has she travelled?
In case anybody wants to try it themselves I have blanked out my answer - If you click and hold your mouse button down on the words "Suggested Answer" below then drag your mouse down the page the answer will be revealed.
Suggested Answer:-
Answer = 57.1111 miles
Using 8x4x5x2=320 as the denominator:
Day1=40/320 of the distance Day2=70/320 Day3=84/320 Day4=63/320
Total travelled = 257/320 leaving 63/320
And 14x257/63 = 57.1111
Congratulations to last month's winners: M Bhave from Reading and N Shrewsbury from Bournemouth. The correct answer was: BYF = 162.
