The two motorcyclists drove out in opposite directions. The speed of the first rider is 20 km / h, and the second is 15 km / h. The distance between them is 10 km and the total length of the route is 80 km. How many hours will it take?
1. Let us determine what distance the motorcyclists must travel if it is said that there are 10 kilometers between them, and the whole path is 80 kilometers.
80 – 10 = 70 kilometers.
2. Let’s calculate which way they pass in one hour of movement.
20 + 15 = 35 kilometers.
3. Find out how long it will take them to cover the track, the length of which is 80 kilometers.
70/35 = 2 hours.
Answer: Motorcyclists will cover the track in 2 hours.
