Answer:
The amount of energy generate by the generators if they work simultaneously for 40 minutes is 1/2.
Step-by-step explanation:
Consider the provided information.
One of the generators produces n units of energy in 4 hours, and the other generator produces the same amount of energy in half the time.
Let the total hours = n
The first generator produces energy in 1 hr = n/4
The first generator produces energy in 1 hr = n/2
Total energy is:
[tex]\frac{n}{4}+\frac{n}{2}=\frac{n+2n}{4}=\frac{3n}{4}[/tex]
Total time taken is 40 mins. Now convert 40 minutes into hours:
40/60 = 2/3 hr
Now to find the amount of energy generate by the generators if they work simultaneously for 40 minutes is:
[tex]\frac{3n}{4}\times \frac{2}{3}=\frac{n}{2}[/tex]
Hence, the amount of energy generate by the generators if they work simultaneously for 40 minutes is 1/2.
