If it were two hours later, it would be half as long until midnight as it would be if it were an hour later. What time is it now?
9 PM
9:30 PM
9:20 PM
none of these
To solve this question, the user needs to use algebraic equations and time concepts. We can start by setting up the equation:
Let x be the number of hours until midnight from the current time. Then, we can create the equation:
(x - 2) = 1/2(x - 1)
Now, we can solve for x to determine the number of hours until midnight from the current time.
x - 2 = 1/2x - 1/2
Multiplying each side of the equation by 2 to eliminate the fraction yields:
2x - 4 = x - 1
Simplifying the equation by combining like terms gives:
x = 3
Therefore, there are 3 hours until midnight from the current time. If we subtract 3 hours from midnight, we get 9 PM. Thus, the correct answer is:
The Answer is: A. 9 PM
