Question

One computer printer can print a company's weekly payroll checks in 60 min. A second

printer would take 90 min to complete the job. How long would it take the two printers,
operating together, to print the checks.
Smart people can you help me again?​

Answer 1

35 mins is the answer.

1/2 +1/3 = 5/6 = 30mins

1/6 remaining is distributed over 5 mins

30/6 =5

30+5 = 35mins
