In a kilometre race a beats b by 1 minute and Beats C by 375m if b beats c by 30 seconds the time taken by C to run 1 kilometre is?

Answers (2)

Let A complete the 1km race in x secondsThen B will be x+60 seconds and thats of C completes (x/625)×1000 seconds.

B beats C by 30 seconds, so x+60+30=1000x/625.    x+90=1000x/625. After simplify x=56250/375=450/3

1000×450/3×625=240 seconds
