Question 749477
Amso can dig a hole in 6 hrs, Ndou candig the same hole in 4 hrs. How long would it take both Amso and Iblis to dig half a hole if they worked together?
----------
In 1 hour, Amso digs 1/6 of the hole, Ndou digs 1/4.
Together, they dig 1/6 + 1/4 = 10/24 holes/hour
--> 24/10 hours/hole
= 2.4 hours
