Given that Phil takes 3 times as long as Meredith to complete the work . Let us take Meredith takes x hrs to complete the work, the Phil will do that work in 3x hrs . Now it is given that they together complete the work in 12hrs . So ,


\longrightarrow (1)/(x)+(1)/(3x)=(1)/(12)\\


\longrightarrow (3+1)/(3x)=(1)/(12) \\


\longrightarrow (4)/(3x)=(1)/(12)\\


\longrightarrow x =((4)(12))/(3)\\


\longrightarrow x = 16\ hrs

Hence,

  • Time taken by Meredith to complete the work alone= x = 16hrs
  • Time taken by Phil to complete the work alone= 3x = 48hrs

And we are done!
