- Train speed
The train speed is decreased from 72 km/h to 36 km/h in 50 seconds. If the train movement is continuously slowing, find the acceleration and the distance it travels. - Car crash
A car crash occurred on the road with a maximum permitted speed of 60 km/h. From the length of the vehicle's braking distance, which was 40 m, the police investigated whether the driver did not exceed that speed. What is the conclusion of the police, assu - Car braking distance
The car brakes with an acceleration of 5 m/s². Determine the stopping distance of the car if its initial speed is a) 54 km/h, b) 108 km/h. Compare the calculated braking distances concerning the given speeds. - Overtaking
On the direct road, the passenger car overtakes the slower bus by starting to overtake 20 meters from the bus and then passing it ahead of it again 20 meters away. The car overtakes at a steady speed of 72 km/h, while the bus goes at a steady speed of 54 - Table leg painting
The carpenter needs to make 4 wooden legs for the table, which have the shape of a regular 4-sided prism with dimensions of 9 cm × 9 cm × 60 cm. He will paint them all over with white paint. How many m² of surface must be painted? - Ping time
Calculate the theoretical ping time between Orlando and Shenzhen, which is 14102 km distant. Ping time measures the round-trip time for small messages sent from the origin to a destination that is echoed back to the source. The name comes from active sona - Water level
How high is the water in the swimming pool with dimensions of 37 m in length and 15 m in width if an inlet valve is opened for 10 hours, flowing 12 liters of water per second? - Two municipalities
The horizontal distance between municipalities is 39 km. The average sinking is 7 per mille. What is the difference in height between these municipalities? - Cross road
From the junction of two streets perpendicular to each other, two cyclists (each on another street) walked out. One ran at 18 km/h, and the second at 24 km/h. How are they away from a) 6 minutes, b) 15 minutes? - Density of the concrete
If the weight of the cuboid-shaped column is 200 kg, find the density of the concrete with dimensions 20 x 20 cm x 2 m. - Container
The container-shaped box with internal dimensions of 3.9 m, 3.25 m, and 2.6 m was completely filled with goods in the same cubic boxes. How long edge could this box have? - Cube volume comparison
There are two cubes. One has an edge of 9 dm and the second of 9 cm. How often does the largest cube have a larger volume than a smaller one? - 3d printer
3D printing ABS filament with a diameter of 1.75 mm has a density of 1.04 g/cm³. Find the length of m = 5 kg spool filament. (how to calculate length) - Decagon
Calculate the area and circumference of the regular decagon when its radius of a circle circumscribing is R = 1 m - Wiring 2
Willie cut a piece of wire that was 3/8 of the total length of the wire. He cut another piece that was 9 m long. The two pieces together were one-half of the total length of the wire. How long was the wire before he cut it? - Running
Joanne ran 8 1/2, Kyleigh 1 2/3, and John 6 3/4 miles in one day. How many miles did the girls run in 3 days? - Circular Track Radius
What circular track radius must a runner run six times to run 1.8 km? - Hectoliters
If a garden barrel with a 90 cm diameter and a height of 1.3 m is filled to 80% of its capacity, how many hectoliters of water is in it? - Rectangles
How many different rectangles with sides integers (in mm) have a perimeter of exactly 1000 cm? (a rectangle with sides of 50 cm and 450 cm is considered to be the same as a rectangle with sides of 450 cm and 50 cm) - Right triangle
Calculate the length of the remaining two sides and the angles in the rectangular triangle ABC if a = 10 cm, angle alpha = 18°40'.
