The snail bought a turbulent and immediately exchanged it for an old one. Suddenly, it crawled 2,376 m/s. If the road was 1,188 m long, how long did it take to get home with the new shell? - Railway vibration speed
The period of the natural oscillation of the railway car is 1.25 s. The length of the rails is 25 m. At what speed does the vibration, caused by the impact of the wheels on the joints between the rails, reach a maximum? Give the result in m/s. - Cyclist circuit meeting
Two cyclists left one place on the circuit facing each other. The first drove at a speed of 32 km/h, and the second at 28 km/h. How long was the circuit if the cyclists met in 5 minutes? - Two places
The distance to the places is 60 km. From A place, a pedestrian came out at a speed of 4 km/h, and at the same time, a car drove against him from place B. What was the car's speed if the pedestrian met him in 90 minutes? - Car tractor pursuit
Behind the tractor, which travels at 12 km/h, they sent a car 3.5 hours later to catch up with him in 45 minutes. What speed does he have to go? Please also explain the procedure. - Cyclist meeting
Martha will leave Včelná on a bicycle at 12 km/h. From Holešovice, which is 32 km from the village of Včelná, at the same moment, Eve will drive towards it at a speed of 18 km/h. How long and where will they meet? - Fuel mileage
