A and B walk around a circular track. A and B walk at a speed of 2 rounds per hour and 3 rounds per hour respectively. If they start at 8 a.m. from the same point in opposite directions, how many times shall they cross each other before 8.30 a.m.? | [
"8",
"5",
"7",
"2"
] | D | Relative speed = Speed of A + Speed of B (? they walk in opposite directions)

Time duration from 8 am to 8.30 am = 0.5 hour
Hence they cross each other 2 times before 8.30 am
