Question 594862
    Willie can do the job in 6 days. Myra can do the same job in 4.5 days. If they work together, how long will it take to complete the job?
.
Let x = time (days) for both
then
x(1/6 + 1/4.5) = 1
multiply both sides by 6(4.5):
x(4.5 + 6) = 6(4.5)
x(10.5) = 27
x = 2.57 days
or
x = 2 days 13 hours and 43 minutes
