A truck set off from point A to point B at a speed of 40 km / h, and 2.5 hours later a motorcycle followed it at a speed of 60 km / h. At what distance from point A will the motorcycle catch up with the truck?

1) 40 km / h x 2.5 hours = 100 (km) – the truck will pass
2) 60-40 = 20 (km / h) – this is how much the speed of the motorcycle is higher than the speed of the truck.
3) 40:20 = 2 (h) – after that much the motorcyclist will catch up with the truck
4) 2 x 60 = 120 (km) – will cover a motorcycle in 2 hours
5) 2 x 40 = 80 (km) – another truck will pass
6) 80 +120 +100 = 300 (km)
