Answer:

2 or 12

Step-by-step explanation:

The answer that we will use this equation 1/t1 +1/t2=1/ttotal

where t1 is the time of smaller pipe while t2 is the of the larger pipe

Given t total =4 while t2 is equal to t2=t1-6

So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4

8( t1-3)=(t1^2-6t1)

t1^2-14t1+24=0

t1=2 or 12
