0 tammie Posted March 5, 2013 Report Share Posted March 5, 2013 50 m when bmad at 100 m (the end), bononova is at 70 m because he has been beat by 30m. which at that time puts phase at 50m because he is 20m behind bononova. Quote Link to comment Share on other sites More sharing options...
0 nakulendu Posted March 5, 2013 Report Share Posted March 5, 2013 Bmad runs 100 m in the time Bonanova runs 70. BMAD's Speed / Bonanova Speed = 100 / 70 Similarly , Bonanova's Speed / Phase's Speed = 100 /80 So BMAD's speed / Phase's speed = 10000/5600 = 100/56 So when BMAD reached finishing line at 100m, phase was at 56 m and hence 44 m behind Quote Link to comment Share on other sites More sharing options...
0 bgm1961 Posted March 5, 2013 Report Share Posted March 5, 2013 (edited) Got the same answer as the others, 44 meters Except I used slightly different math: bonanova ran at 70% of Bmad's speed. Phase ran at 80% of bonanova's speed. .70 x .80 = .56 100 meters x .56 = 56 meters, which is then subtracted from the 100 meter race distance to yield the 44 meter answer.
