Problema Solution
It takes joan 3 times longer than jane to file reports, together they can file the reports in 15 minutes. how long would it take each woman to file the reports by herself.
Answer provided by our tutors
let 'x' represent the amount of time it takes for jane to file a report, then '3x' represents the amount of time joan takes
1/15 = 1/x + 1/3x
solving for 'x' we have x=20
3*20 = 60
It takes Jane 20 minutes to file a report and it takes Joan 60 minutes to file a report
