B Correct answer
Explanation

Ratio of speeds A:B = 5:6. Speed of B = 90 kmph. Speed of A = (5/6) * 90 = 75 kmph. Relative speed = 75 + 90 = 165 kmph. Time = Distance / Relative speed = 88 / 165 hours = 8/15 hours. 8/15 * 60 = 32 minutes.

AI explanation

Using the speed ratio of 5 to 6, if car B has a speed of 90 kmph, car A has a speed of 75 kmph. Their relative speed when moving towards each other is 165 kmph. They need to cover a distance of 88 km, so the time taken is 88 divided by 165 hours. Converting this to minutes by multiplying by 60 gives 32 minutes.
