The distance between 2 persons is 800m. If they start moving towards each other simultaneously at 10m/s and 15m/s, in how much time do they meet?

• they will meet after (800/25)=32 sec
  coz they are moving in relative velocity (10+15)=25m/s

• 
  32 minutes

• combined velocity is 25 m/s
  distance=800m
  time=800/25
  =32 sec

• In 1 hr both two person can complete 25 m/s.
  total distance is 800 m.
  so,
  time=distance/speed
  time=800/25=32 seconds

• 35
  800/10+15 =35

  25 because moving towards each other

• 300 percent sure the answer will be 32

• very easy
  10+15=25
  Hence 800/25=32

• in 30s a will be 300m ahead and b will be 450m ahead(300+450=750)
  and in another 2s a will be 20m and b will be 30m (20+30=50)
  in 32s (750+50=800m)
  ans is 32s

• time=distance/relative speed
  =800/25
  =32sec
