A Correct answer
Explanation

Let distance be D. Time1 = D/3, Time2 = D/4. Difference is 4 minutes (2 min late + 2 min early) = 4/60 hours = 1/15 hours. D/3 - D/4 = 1/15 => D/12 = 1/15 => D = 12/15 = 4/5 km.

AI explanation

Using the formula Time equals Distance divided by Speed, the time difference between the two speeds is 2/60 plus 2/60 hours, equaling 1/15 of an hour. The equation is Distance/3 minus Distance/4 equals 1/15, which simplifies to Distance/12 equals 1/15. Multiplying 12 by 1/15 yields a distance of 4/5 km.
