2 cities M and N.Q leaves the city M after 4hrs when P started.P and Q reach N simultaneously.if the speeds of one vehicle is moving with 10kmph more than the other.

• time=dis/speed
  4=d/x+(x+10)
  4(x+(x+10)
  x=5
  speed1=5, speed2=15
  d=time*(speed1+speed2)
  4*20=80

• Let total time 4+y
  x(4+y)=(10+x)y
  4x=10y
  So, we should have either x or y question incomplete
