It is given that the speed of Ravi is
40kmph, which is equal to
m/ s. It is also known that the speed of Ashok is
50kmph, which is equal to
m/ s.
It is known that the distance between Ravi and Ashok is 225 meters, and the relative speed of Ravi and Ashok is
+=25m/ sHence, they will meet each other in
=9 seconds. The distance traveled by Ravi in these 9 seconds is
×9=100 meters.
Since Vijay was already 54 meters behind Ravi when they were starting, Vijay must travel
(100+54)=154 meters in these 9 seconds.
Hence, the speed of Vijay is
m/ s, which is equal to
×==61.6kmph.
The correct option is C
