Answer:
25 minutes
Step-by-step explanation:
Worker1 is filling up at a rate of 11 per minute while worker2 is filling up at a rate of 11+1 per minute. Since worker1 has 25 extra barrels and since worker2 makes one extra barrel per minute it will take exactly 25 minutes to match worker1's barrel count.
No that would be cheating
Are you asking me to demonstrate how to handle that equation ?
Are you expecting to get the procedure and solution here ?
If you were asking a question, would that be it ?
Well, OK. You manipulated me into it.
5p + 2 = 4p - 1
Subtract 4p from each side: p + 2 = - 1
Subtract 2 from each side: p = - 3
Answer:
it is 12
