Two objects A and B having velocities 20 m/s and 10 m/s respectively are 500 meters apart start to travel in same direction. After what time (in seconds) will they meet each other

I will assume the slower one is in front  o/w they will never meet

 

the 20 m/s one is traveling 10 m/s faster than the other one and will eat up that 500 m separation in 500 m /10 m/s= 50 seconds
