A can run 3 Kms in 3 min 18 sec and B can run same distance in 3 min 40 sec, then by how much distance A can beat B?

a. 300 m
b. 220 m
c. 280 m
d. 195 m

• Distance travelled=3000m
  Time taken by A=3 m 18 s
  Time taken by B=3 m 40 sec=220 sec
  speed of B=3000m/220 s=150/11 m/s
  Difference between time of A and B=22 sec
  when time will be 3 m 18 s A will have travelled 3000m but B need 22 sec more to finish.
  Distance travelled by B in 22 sec=(150/11)*22=300 m
  Hence, A beat B by 300 m.

• A 198 sec --> 3000 mtrs (3km)
  
  B 220 sec --> 3000 mtrs(3km)
  198 sec--> x mtrs
  
  x*220=3000*198
  x=300*9
  x=2700
  B can run 2700 mtrs in 198 sec
  
  A-B=>3000 - 2700=>300 mtrs

• 3km=3000m
  difference is 22 second
  3 min 40 s== 220 sec
  so, 3000*22/220==300 ans

• B can cover 3000m in 220sec
  A can cover 3000m in 198sec
  
  --> B can cover x m in 198sec
  3000m --> 220sec
  x m -->198sec
  x=2700
  
  difference=3000-2700=300m
  ans is 300m

• 3 min 40 sec = 220 sec
  3min 18 sec = 198sec
  time diff = 22 sec
  dist=3000m
  dist/time =3000/220=150/11
  so in the additional 22 seconds B lacks behind by 300m

• 3kms=3000m
  3min 40 sec=3*60+40=220sec
  3min 18sec=3*60+18=198sec
  therefore D=?
  we know that dis =3000m
  so
  3000/220*198=2700
  SOLUTION:3000m-2700m=300m
  distance that A can beat B is 300m

• 3000---------198sec-->A
  3000---------220sec-->B
  198 sec both travel then for 22 sec of bis travel =300mts

• 300
  speed of A=3000/198 m/s
  speed of B=300/220 m/s
  difference in time to cover same distance= 40-18=22sec
  distance travelled by B in 22 sec=(3000/220)*22=300 m
