A computer operator typing a manuscript at a speed of 1 page in 10 minutes finished the work in 3 hours. How many hours will he finish the work if he spends 2 minutes less on each page?
Let’s translate 3 hours into minutes: 3 hours = 180 minutes;
180/10 = 18 pages in work,
1 page = 10-2 = 8 minutes will be spent on each page.
Let’s find the time it takes for the operator to finish work: 18 * 8 = 144 minutes = 2 hours 14 minutes
Answer: 2 hours 14 minutes
