A car ‘A’ leaves city X at t=0sec and moves with a constant velocity of 40km/hr due west. Another car ‘B’, leaves city Y which is 30km south-west of X, 0.5 hours after A leaves X and moves with 20* (2^(1/2)) km/hr towards north-west. Then: > Minimun separation during the journey will be 20km > Minimum separation will be at t = 1/(2*(square root of 2))hour > They strike each other at t = 3/(2*(square root of 2) hours > None of these
