Aaron and Kit can finish their CLE subject in 15 and 16 days respectively. If these two learners work together, how many days can they finish their CLE subject?

Sagot :

Rate of Aaron: 1/15
Rate of Kit: 1/16

Let 1/t be the rate if they work together:
1/15 +1/16 = 1/t

31/240 = 1/t

t= 240/31

Therefore, together they can finish it in 240/31 days (less than 8 days)
