Mr. reyes can dig a ditch in 6 days and mr. Cruz in 8 days. In how many days can both men dig the ditch together?

Answer provided by our tutors

Mr. Reys will dig 1/6 of the ditch in 1 day


Mr. Cruz will dig 1/8 of the ditch in 1 day


If they need 'x' days to finish the job working together then we can write:


x/6 + x/8 = 1


By solving the equation we get


x = 4 days


They need 4 days to finish the job together.

If they need 'x' days to finish the job working together then we can write:


x/6 + x/8 = 1


By solving the equation we get


x = 24/7 days = 3.42 days approximately


They need 3.42 days approximately to finish the job together.
