In a 100 m race A beats B by 15 m,B beats c by 10 m. If A beats C by 5 sec.Then find the speed of C.

• ans should be 4.7m/s
  because A:B is 100:85
  B:C is 100:90
  so A:B:C is 100:85:76.5
  so C lags by 23.5m from A and which he covers in 5 sec so speed is 23.5/5=4.7

• devika here is the ans 4 ur question
  
  a:b=100:85
  b:c=100:90
  now 100:85
  100:90
  we need to equate dem..by making b value equal in both equations..so multiply eq1 by 100 and eq2 by 85...dis becomes
  10000:8500
  8500:7650
  => 10000:8500:7650
  => 100:85:76.5

• A beats by 15 m B beats by 10 m C
  A beats C 5sec
  distance b/w A and C is 25 m
  so speed of c=total distance/total time
  c=25m/5sec=5 m/sec
  Ans:5m/sec

• hi lucky, how 100:85 and 100:90 become 100:85:76.5?
• 11 years agoHelpfull: Yes(2) No(1)
• distance b/w A and C is 25 m and time is 5sec
  then use the formula speed*time=distnace then get the ans 25/5=5m/s
