Numericals on Relative Velocity

1. Two cars are moving in the same direction with speed 30 km/hr. they are separated by a distance of 5 km. what is the speed of a car moving in the opposite direction if it meets these two cars at an interval of 4 mins?

2. A police van moving at a speed of 30 km/hr fires a bullet at a thief’s car moving at a speed of 190 km/hr. if the muzzle speed of the bullet is 150 km/hr, find speed of the bullet the thief’s car will observe.

3. Three boys A, B and C are situated at the vertices of an equilateral triangle of side ‘d’ at t=0. Each of the boys moves with constant speed ‘v’. A always moves towards B, B towards C and C towards A. At what time and where will they meet each other?
