A good question. Let t be the number of minutes it is now before 5 p.m., making the time now 5:00 – t. So the time of “equality” was at 5:00 – t – 30. At that time, it was 3:00 + 4t, correct? The equation would read 5:00 – t – 30 = 3:00 + 4t. You can’t really work with the “o’clock” numbers, so let’s change them to minutes past noon. 3:00 would be 180, and 5:00 would be 300. Now the equation reads 300 – t – 30 = 180 + 4t. That looks better. Simplify the left to 270 – t, then add t to both sides. Now we have 270 = 180 + 5t. Subtract 180 from both sides, and 90 = 5t, so t = 18.
So the time now is 18 minutes before 5. To check, we need to go back to the time of equality, 30 minutes ago. That would be 12 minutes after 4, or 252 minutes after noon. Is that equal to 4 x 18 minutes after 3? 180 + 72 = 252! That’s it!
