A cyclist and a motorcycle rode out of two villages at the same time towards each other. The cyclist is at 15 km / h and the motorcyclist is at 57 km / h. The distance between the settlements is 288 km. What is the distance between them 3 hours after the start of the movement?

Let us solve the problem using the distance formula P = C * in, where P is the distance, C is the speed of movement, and in is the time of movement.
1) 15 * 3 = 45 (km) – this distance was covered by the cyclist 3 hours after the start of the movement.
2) 57 * 3 = 171 (km) – this is the distance the motorcycle traveled 3 hours after the start of the movement.
3) 45 + 171 = 216 (km) – such a distance traveled by a cyclist and a motorcyclist in three hours, and this distance – by which the distance between villages was reduced during these three hours.
4) 288 – 216 = 72 (km) – the distance between the motorcycle and the bicycle 3 hours after the start of the movement.
Answer: 72 km
