This is an indirect proportion. This is how I solve it:
First, we need to know the rate of one worker, and this is equal to
. This means he completes 1/10 of the work in a day.
So since Distance= Rate * Time (Think of distance as the reciprocal of the number of workers), we would have:
So we take the reciprocal which is 1/5 or 0.2 so we have 0.2 workers. (Are you sure that the given is ;ike this?)
