Frank can type a report in 2 hours. James takes 4 hours to type it. How long will it take the two of them typing together?

frank has double speed then james 


so we simply take average to calculate speed of both togather typing = (4+2)/2 =3 hours

so it will take 3 hours both of them typing togather
