You can put this solution on YOUR website! Let time taken by Emily be x
then alieen take 2/3 of x = 2x/3
1 min work of emily = 1/x
1 min work of alieen = => 3/2x
i min work of both = 1/45
1/x + 3/2x = 1/45
5/2x = 1/45
1/x = 2/225
Emily take 225/2 mins to complete the work, then alieen = 225/2*2/3 = 75 mins
