10. Mowing a lawn Joe can mow a lawn in 4 minutes less time than his sister Karen. Together they can

finish the job in 20 minutes. How long would it take Karen if she worked alone?

It’s on my test, and my teacher is asking for test corrections, can Simone explain please?

about 24 minutes? because together it would take about 12 mins for her and 8 mins for Joe. then she has to do double the work making it 24. That’s an educated guess sooooo.
