I don't see why this is on a computer section but either way I would chose D because naturally when you park on a hill you would be cautious about your car going into motion down the hill so therefore you would think of which way gravity would pull your vehicle
Answer:
8/3 hours
Explanation:
For this question, let us say that 1 job contains 240 files
Computer X does this job in 4 hours
Computer Y does the same job in 8 hours
All we need to find is how long it will take both computers to finish the job
Now we apply the basic combined work formula, which is
Combined Time = (time a * time b)/(time a + time b)
And we known that time a = 4 hrs,
We then substitute this values into the equation to get
Combined time = (4*8)/(4+8)
= 32/12
= 8/3 hours
