Question 35287
Set-up the problem as follows:

x/6 + x/4 = 1 (one entire job)

Simplify and solve for "x"

(6x + 4x)/24 = 1

10x/24 = 1

x = 24/10

x = 2.40 hours

Convert .40 hours to minutes by using the conversion factor of 60 minutes/1hour:

.40hours x (60min)/(1hr)= 24 minutes

So both men would complete the job in 2 hours and 24 minutes.
