Answer: 0
Step-by-step explanation: The integers that lie between -2 and 1 are -1 and 0.
∴ The product of -1 and 0 = -1×0 = 0
For this case, what we can do is calculate an average of the time it takes to fill the tank for both pipes.
We have then:
taver = (tA + tB) / (2)
Where,
taver: average time (both pipes)
tA: time it takes the pipe A
tB: time taken by pipe B
Substituting the values:
9.9 = (18 + tB) / (2)
Clear tB:
tB = (2 * (9.9)) - 18
tB = 1.8 hours
Answer:
it takes pipe B, running alone, to fill the tank about 1.8 hours
