D Correct answer
Explanation

Relative speed = 55 + 80 = 135 km/hr. Time = 1 hour 36 minutes = 1.6 hours. Distance = Speed * Time = 135 * 1.6 = 216 km.

AI explanation

Using the relative speed formula for two bodies moving towards each other, their relative speed is 55 + 80 = 135 km/hr. The total time taken to meet is 1 hour and 36 minutes, which equals 1.6 hours. Multiplying the relative speed by the time gives the total distance as 135 * 1.6 = 216 km, so the result is 216.
