Punit goes from his home to his relative's place at a speed of 45 km/h. While returning from the relative's place, due to traffic, it takes him an hour longer as he can only drive at the speed of 40 km/h. Find the distance (in km) of his relative's place from his home.

Direction: What value will come in place of the question mark (?) in the following question?

100, 108, 120, 136, 156, ?
