Sam can do a job in 4 days
Lisa can do a job in 6 days
Tom can do a job in 2 days
How long can Sam Lisa and Tom complete the job?
.8 1.09 1.23 1.65 1.97
I cannot remember how to start this problem can somebody please help me
Sam does 1/4 of a job per day (job per day is like miles per hour, if you want to think of it that way)
Lisa has a speed of 1/6 of a job per day
Tom has a speed of 1/2 of a job per day
So, they complete the job amount of days later...
Let's solve for n, first we multiply both sides by 12 to get:
So they can finish the job in
