Tom can finish a piece of work in 11 days. After he has worked for 2 days, Mike joins him and together they finish the work in 6 more days. In how many days could Mike finish the work by himself?
***
let x=number of days Mike could finish the work by himself
1/x=Mike's work rate
1/11=Tom's work rate
6(1/x)+8(1/11)=1
6/x+8/11=1
6/x=1-8/11=11/11-8/11=3/11
x/6=11/3
3x=66
x=22
number of days Mike could finish the work by himself=22
