Question

A can dig 1/12
of a trench in 1 day, while B can dig 1/6 of the trench in 3 days. If they work
together, how long will they take to dig the whole trench?​

Answer 1

Answer:

6 days

Step-by-step explanation:

Speed of A = 1/12 per day

Speed of B = 1/6 in 3 days

so 1/6 divided by 3= 1/18 per day

1/12 +1/18= 6/36=1/6 per day

1/6 mutiplied by x = 1(Whole trench)

x=6

So, 6 Days
