A motorcyclist left town A to town B at a speed of 72 km / h. Three hours later, a bus came out of town B at a speed of 55 km / h and met a passenger train 5 hours after the exit. Find the distance between the cities.
We will find out what time the motorcyclist was on the road before the meeting.
3 + 5 = 8 (h) – the travel time of the motorcyclist.
Let’s find what distance the motorcyclist traveled.
The rider’s speed must be multiplied by the travel time.
72 * 8 = 576 (km) – the path of the motorcyclist.
Let’s find the distance the bus traveled to the meeting.
The speed of this bus must be multiplied by the travel time.
55 * 5 = 275 (km) – the bus passed.
Let’s find the distance between the cities.
576 + 275 = 851 (km)
Answer: 851 kilometers distance between cities.
