Frank can type a report in 3 hours and james can type a report in 4 hours. How long will it take them to type?

Frank 1/3 report per hour

James 1/4 report per hour

So together they type 7/12 of a report per hour

1 or 12/12 divided by 7/12 equals 1 and 5/12

5/12 of 60 is 42 minutes and 48 seconds

So the answer is 1 hour 42 Minutes and 48 seconds

Frank can type 1/3 of the report per hour,James can type 1/4 of the report per hour. Working together they can type 7/12 of the report done in 1 hour. Working together they can complete the report in 1 hour and 50 minutes.

it will take James 4 hours and Frank 3 hours. I am assuming they are not working on this together.

Taking into consideration that 2 can not get along.By the time they decide how to edit etc,

I would say 52 hours and 31 minutes.If a miracle occurs

One hour 33 minutes 33 seconds point 3333333333.

divide the record between them. Frank receives by ability of his project in a million½ hours; James receives by ability of in 2 hours. the completed element has been finished in 3½ hours. i'd hate to work out the record!

Four hours and three hours respectively. Sorry, I don't really know.
