If the two objects move in opposite direction at different speeds
If the speed of 1st object = x km/hr and
Speed of 2nd object = y km/hr
Therefore, their relative speed = (x + y) km/hr
We know, speed of one object with respect to another is called relative speed.
If distance between them = d km, then
Time after which the two objects meet = d km/(x + y) km/hr
If time after which they meet is given i.e., time = t hours
Then distance covered in ‘t’ hours = time × relative speed = t hours × (x + y) km/hr
If the speed of 1st object = x km/hr and
Speed of 2nd object = y km/hr
