The distance between motorcyclists moving towards each other is 1100m. Determine where and when they will meet, if the speed of the 1st is 40 km / h, and the 2nd is 32 km / h.
Data: S (reference distance between riders) = 1100 m; V1 (speed of the first rider) = 40 km / h (in SI V1 = 11.11 m / s); V2 (speed of the second rider) = 32 km / h (in SI V2 = 8.89 m / s).
1) The meeting time of the considered motorcyclists: t = S / (V1 + V2) = 1100 / (11.11 + 8.89) = 55 s.
2) Meeting point:
a) the distance covered by the first rider: S1 = V1 * t = 11.11 * 55 = 611 m.
b) distance covered by the second rider: S2 = V1 * t = 8.89 * 55 = 489 m.
