Question

How can we have different speeds relative to a same point for a same object?

Answer 1

If two objects move in same direction at different speeds

If speed of 1st object = x km/hr and

Speed of 2nd object = y km/hr

Therefore, their relative speed = (x – y) km/hr [x > y], then

Time after which the two objects meet = distance / relative speed = d km/ (x – y) km/hr

We know, speed of one object with respect to another is called relative speed.

If time after which they meet is given, i.e., time = t hrs.

Then, distance covered in ‘t’ hours = time × relative speed  = t hours × (x – y) km/hr

Answer 2

$<marquee><b>Two Objects Move in Same Direction. We know, speed of one object with respect to another is called relative speed. ... Twoathletes are running from the same place at the speed of 6 km/hr and 4 km/hr. find the distance between them after 10 minutes if they move in the same direction.$
