The length of the path between the cities is 360 km, the bus takes 6 hours, the scooter takes 12 hours.

The length of the path between the cities is 360 km, the bus takes 6 hours, the scooter takes 12 hours. How many hours will the meeting between the bus and the scooter take place if they simultaneously enter from these cities towards each other.

1. We calculate with what speed the bus was moving:
360: 6 = 60 km / h.
2. We calculate the speed of the scooter:
360: 12 = 30 km / h.
3. We accept for x time, after which the bus and the scooter will meet.
4. The bus will travel 60 km, a scooter 30 km.
5. Considering that the total length of the path of vehicles is equal to the distance between cities, we compose the equation
60x + 30x = 360;
90x = 360;
x = 4 hours.
Answer: the bus and the scooter will meet 4 hours after leaving their cities.
