    A one km long train was fast approaching Tunnel no.1, at a distance of 2 + 3/4 km (two and three quarters )km; Tunnel no.1 is 1.5 km long.
    Further at a distance of 1.75 km Tunnel no. 2 is located , which is of length 1 + 1/2 km.(one and a half )km.
    Further at a distance of 2.5 km Tunnel no. 3 is located and it is of length 1 km.
    Find the time elapsed when the train had completely passed through Tunnel no. 3 ,
    If the train took 2.5 minutes to pass through 1 km , uniformly .
