let t time is taken for overtake,and x is the total distance to overtake.

distance travelled by blue car in t sex is (x-5)m

distance travelled by red car in t sex is (x+5)m

 t=(x-5)*1000/42 =(x+5)*1000/60........(1)

  or (x-5)/42=(x+5)/60

calculate x from here. this is the required distance.

and put this value in eq (1) and calculate t .
