An experienced bank auditor can check a bank's deposits twice as fast as a new auditor. Together it takes the auditors16 hours to do the job. How long would it take the expirienced auditor working alone?
An airplane flies 490 miles with the wind and 330 miles against it for the same length of time. If the speed of the wind is 20, what is the speed of the airplane in still air?
Thank you!
