sorry I didn't know you had any
Given :- Jamie sorts 3 bins in 2 hours and adam sorts 3 bins in 3 hours.
To Find :- if they work together, how long would it take them to sort 3 bins ?
Solution :-
→ Jamie sorts bins in 2 hour = 3
→ Jamie sorts bins in 1 hour = (3/2) = Efficiency .
similarly,
→ Adam sorts bins in 3 hour = 3
→ Adam sorts bins in 1 hour = (3/3) = 1 = Efficiency .
then,
→ Number of beans they sort per hour together = (3/2) + 1 = (5/2) beans .
therefore,
→ Time taken by them to sort 3 bean = 3 / (5/2) = 3 * (2/5) = (6/5) = 1.2 hours (Ans.)
