If you liked this problem, here is an NRICH task which challenges you to use similar mathematical ideas.
Answer: point A
Same distance: Nikki needs $\frac13$ of the time Malcolm needs
Same time: Nikki runs $3$ times further than Malcolm
Distances in ratio Nikki $:$ Malcolm = $3:1$ so they meet at point A
