You can put this solution on YOUR website! Frank can do in 8 days a task which he and James together can do in three days. How many days would be required for James to do the work alone?
let 1/x=james'work rate
1/8=frank's work rate
1/3=work rate frank and james working together
..
sum of indv. work rates =work rate working together
1/x+1/8=1/3
1/x=1/3-1/8=8/24-3/24=5/24
x=24/5=4.8
How many days would be required for James to do the work alone? 4.8
