let at t hour they cross each other
hence ,
distance covered by first bus at t time +distance covered by 2nd bus at t time
=distance between anandpur and shivnagar
45t km + 40t km =225 km.
=> 85t km =225 km
t=45/17 hours =2 hour 38.6minutes
hence they cross each other at 2:38.6pm
now ,
they cross from anandpur to 45 x 45/17
=2025/17 km
hence ,
distance covered by first bus at t time +distance covered by 2nd bus at t time
=distance between anandpur and shivnagar
45t km + 40t km =225 km.
=> 85t km =225 km
