- Boat water speed
The water in the river has a speed of 4.8 km/h relative to the bank. A boat in still water has a speed of 12.6 km/h. a) What is the boat's speed relative to the shore if it is sailing downstream and upstream of the river? b) What path will the boat travel - Pavol 3
Pavol and Roman trained on a running track of length 400 m. At a certain moment they ran from the start in the same direction and ran at a uniform motion. When Pavol, after completing five laps in time 6 min 40 s, passed the starting point again, he overt - Two friends
Michael and Teresa have the same 9 km long journey home from SNP Square. It takes Michael an average of 2/5 hours by tram, and Teresa rides a bicycle at an average 18 km/h speed. Guess who comes home early and how much? - Cannon sound speed
A cannon fired at a distance of 2720 m from the observer. The sound of the shot was heard by the observer 8 seconds after the flash. Calculate the speed of sound propagation in the air if we assume that the observer saw the flash at the same time as the s - Car average speed
A car drives for an hour on the highway at a speed of 100 km/h, then for half an hour at a speed of 80 km/h, and for another half hour in the field at a speed of 20 km/h. What track did he run together? What is the average speed of the car? - Mr. Quick
Mr. Rychlý needs to drive from Brno to Prague. There is an oversized load on the D1 motorway, which leaves Brno at 11:00 p.m. at a speed of 12 km/h. What is the latest time Mr. Rychlý can depart to avoid getting caught behind the load, i.e. to reach the H - Satellite runway speed
The satellite flies at a speed of 8 km/s. Will it fly down the runway in two seconds? - Three-day trip
George went on a moped for a three-day trip. He drove 90 km on the first day, 30 km on the second day, and 60 km on the third day. He always drove at the same average speed and always the whole number of hours. Calculate the average speed if George drove - Perpendicular roads
Two roads meet at a right angle. On one road there is place P at 5 km from the intersection, on the other road there is place R at 12 km from the intersection. Places P and R are connected by a direct path. A pedestrian goes from place R to place P along - Car intersection speed Two cars started from the right-angled intersection of two roads. The first at a speed of 80 km/h and the second at a speed of 60 km/h. How fast are they moving away from each other?
- Tourist distance time
The tourist walked 1/4 of the way at a speed of 4.5 km/h, 2/5 at a speed of 4 km/h, and the remaining 7 km at a speed of 5 km/h. How many kilometers did he run, and how long did the journey take him? Calculate the time in a fraction. - Bus car pursuit
At 7:30 AM, the bus left at a speed of 45 km/h, and at 8:00, a car behind it started at 65 km/h. Where and when did they meet? - Car meeting location Cars left two places 520 km apart simultaneously at speeds of 30 km/h and 50 km/h. Where and when will they meet?
- Beetle cabbage pursuit
Theodore the beetle set off from the house towards the cabbage leaf at a 20 m/min speed. Two minutes later, Max the beetle followed him at 24 m/min speed. They both came to the cabbage leaf at the same time. How far was the cabbage leaf from their house? - Car distance remaining The car travels from Prague to Brno at a speed of 80 km/h and still has 15 minutes to drive. How far is it from Brno?
- Train
A train moves along a track at constant speed v0 for a time t1 = 1.00 h, but then it must stop due to works on the track and waits at the place for a time t2 = 0.50 h. When it gets moving again, its constant speed is only 75% of the original speed v0. The - Doppler effect
The observer moves away from the source at a speed of 12 m/s. The source produces sound with a frequency of f=475 Hz. What is f2 (frequency of sound perceived by the observer)? v= 340 m/s. - Airplane distance meeting
Two points are at a distance of 1840 km. An airplane departs from A at 7:00 a.m. and flies at an average speed of 50 km/h faster than another airplane departs from B at 8:00 a.m. At what distance from A do they meet at 9:00? - Coefficient of friction A car moves along a horizontal road at a speed of 15 m/s. After turning off the engine, the car traveled a distance of 225 m. What was the coefficient of friction for this motion?
- Bus highway speed Tourists traveled by bus to Croatia. They drove the highway in 8 hours at an average speed of 100 km/h. How fast would they cover it if they walked at an average speed of 120 km/h?
