Question 964408
A watch looses x minutes every y hours.
 At this rate, how many hours will the watch lose in one week ?
:
{{{x/y}}} = no. min lost per hr
Find no. hrs in 1 week: 24*7 = 168 hrs
therefore
{{{(168x)/y}}} = no. of min lost in 1 week
{{{(168x)/(60y)}}} = {{{(42x)/(15y)}}} = no. of hrs lost in 1 week
