Question

two boys start running together from the same place with speeds 6km/hr and 4km/hr respectively.find the distance between them after 6 minutes , if they run
in the same direction
in the opposite direction

i need the answer urgently

Answer 1

If it's in the same direction their relative speed is 6-4 = 2 kmph = 1/30 km/min.
So, after 6 min distance between them is 1/30 * 6 km = 200 m.
In case they run in the opposite direction, their relative speed is 6+4 = 10 kmph = 1/6 km/min.
That means after 6 min they are separated by 1/6 * 6 = 1 km.
