Sound travels in the air at a speed of 330 m/s. Build a table of the dependence of the distance that the sound travels in a given time (for 1 to 10s, one second at a time). Write the equation of the relevant dependence. - Motion against
From two places 36 km apart, a pedestrian and a cyclist will go straight opposite each other. How long will they meet if the speed of the pedestrian is 4 km/h and the cyclist 12 km/h? - The train
The train passed the observer in the 20s and passed through a 1500m tunnel in 2 minutes. Calculate the speed (km/h) and train length. - Railroad
The railroad runs parallel to the railway. The train travels at 36 km/h on track. In the opposite direction, the motorcycle rides at 90 km/h. The train passes in 3 seconds. How long is a train?

An airplane flew from city A to city B at a speed of 500 km/h. Fifteen minutes later, an airplane took off from city B to city A at a speed of 450 km/h. After 45 minutes, the planes met. Determine the distance between A and B.
- Average 5665
At 10:00 AM, two cars drove against each other from places 240km away. One was driving at an average speed of 70km/h. What was the speed of the other when they met at 11:30? - A truck
A truck left Znojmo at 7 am. He drove to Ostrava at an average of 56 km/h. 15 minutes later. A car went out of Ostrava at the same route from Znojmo at 64 km/h. What time did both vehicles pass and at what distance from Znojmo, if you know that the road d - Increase 5613
The tourist goes at an average speed of 3.5 km/h. The last train takes him 50 minutes. How much does he have to increase his speed if he still has 5 km to go to the station? - Thunder and lightning
There was a glimpse of the sky, and we heard thunder in 4.5 seconds. The light spreads at 300,000 kilometers per second, so we can assume the flash instantly without delay. However, the sound's speed is much lower in the air, one-third of a kilometer per - Distance 5565
