From the village to the city, the distance between which is 126 km, a cyclist left at a speed of 18 km per hour.

From the village to the city, the distance between which is 126 km, a cyclist left at a speed of 18 km per hour. After 4 hours, a bus left in the same direction, which arrived in the city at the same time as the cyclist. How fast was the bus traveling?

Let’s solve this task in action. 1) 4 * 18 = 72 kilometers – the distance traveled by a cyclist at a speed of 18 kilometers per hour in 4 hours; 2) 126 – 72 = 54 kilometers – the distance left for the cyclist to travel when the bus left (as the entire distance from the village to the city is 126 kilometers); 3) 54:18 = 3 hours – the time the bus was on the way; 4) 126: 3 = 42 kilometers per hour – bus speed. Answer: 42 kilometers per hour.
