Delhi is at a distance of 200km from Ambala . A sets out from ambala at a speed of 30km/hr and B sets out at same time from Delhi at a speed of 20 km/hr . They will meet each other after what time?
plzz answer fast.. upto tmrw.. dr is xm on tuesday
Relative velocity = 30 km/hr + 20 km/hr = 50 km/hr (Since, they are moving in opposite directions)
Total distance = 200 km
Time after which they will meet = 200/50 = 4 hrs.
