A worker can do a work in 18 days . An oher worker can do the same work but in 24 days ,and another in 30 days . If the 3 workers work 6 days altogether what part of the work will be done ?
How would I solve this for kj?:
ln(kj/15) = 2ln(kj/60)
The answer is kj = 240, but I am unsure as to how to get there. Thanks for your help.
