_______________speed____________time___________distance
Tom______________r______________25%2F60__________(____)
Louis___________10______________10%2F60___________d=10%2A10%2F60=5%2F3


Nothing was indicated about their directions or routes. This solution will assume that they each go the same distance.

Once found Louis distance, we know Tom's distance may be equal, so

_______________speed____________time___________distance
Tom______________r______________25%2F60__________(5%2F3)
Louis___________10______________10%2F60___________d=10%2A10%2F60=5%2F3

Finding Tom's rate, r, is simply a matter or Rate*Time=Distance, solved for Rate.
r%2825%2F60%29=5%2F3
r%285%2F12%29=5%2F3
r=%285%2F3%29%2812%2F5%29
r=12%2F3=4+
4 kilometers per hour



-Note, 1 hour = 60 minutes
