| **Two cars left points A and B in the same direction at the same time: from point A – a passenger car, and from point B – a truck. The speed of the truck is 45 km / h. What is the speed of a light car if it caught up with a cargo car 4 hours after departure, and the distance between points A and B is 156 km?**

1) 45 * 4 = 180 (km) – the truck drove in four hours

2) 180 + 156 = 336 (km) – overcame a passenger car in four hours

3) 336: 4 = 84 (km / h) -speed of a car

Answer: the speed of a passenger car was thirty-two kilometers per hour, taking into account the fact that the passenger car caught up with the truck in four hours, again taking into account the fact that the distance between points A and B was 156 km.
