Question 533309
Tom and Shondra can complete a job working together in 4 hours. If Shondra takes 6 hours to do the job alone, how long would it take Tom to complete the job alone.
**
1/6=sondra's work rate
1/x=Tom's work rate
1/4=Work rate working together
..
sum of individual work rates=work rate working together
1/6+1/x=1/4
1/x=1/4-1/6=3/12-2/12=1/12
x=12
ans:
It would take Tom 12 hrs to complete the job alone.
