- Water current
John swims upstream. After a while, he passes the bottle, and from that moment, he floats for 20 minutes in the same direction. He then turns around and swims back, and from the first meeting with the bottle, he sails 2 kilometers before he reaches the bo - Average speed
The average speed of a pedestrian who walked 10 km was 5km/h, and the average speed of a cyclist on the same track was 20km/h. In how many minutes did the route take more than a cyclist? Q - The fastest
The fastest boat can reach speeds more than 710% as fast as the Queen Mary 2. How would you express this number as a fraction and as a decimal? - Skid friction
Find the smallest coefficient of skid friction between the car tires and the road so that the car can drive at a 200 m radius at 108 km/h and does not skid. - The bridge
A vehicle weighing 5,800 kg passes 41 km/h on an arched bridge with a radius of curvature of 62 m. What force pushes the car onto the bridge as it passes through the center? What maximum speed can it cross over the bridge's center so it does not fly off t - Angled cyclist turn
The cyclist passes through a curve with a radius of 20 m at 25 km/h. How much angle does it have to bend from the vertical inward to the turn? - Rotaty motion
What minimum speed and frequency do we need to rotate with the water can in a vertical plane along a circle with a radius of 70 cm to prevent water from spilling? - Government 14723
Vlado moves at a speed of 4 km/h. Its step is 0.8 m long. How many steps will the government take in 12 minutes? - Two trains
Two trains departed from City A and City B against each other. They met after some time. The first train took 9 hours to reach city B, and the second took 4 hours to reach city A. In what proportion were the train speeds? - Motion
The two bodies move in the same direction evenly in a straight line, at speeds of 5 cm/s and 10 cm/s. The movement of the first body started 2 seconds earlier than the movement of the second body, from a point located at a distance of 20 cm from the start - Escaping 14483
The rocket develops a higher speed, which is: a) higher velocity of escaping gases b) higher mass of escaping gases c) greater momentum of escaping gases d) shorter rocket length - Equal temperature
We measured the temperatures of the two cities simultaneously. The temperature in town A was 60 degrees and rose at a constant rate of 2 degrees per hour. The temperature in city B was 40° and rose at a constant rate of 10° per hour. Find the time in hour - A cold front
At 1:00 PM, the temperature was 46 degrees. Then, a cold front moved in and decreased the temperature by 12 degrees per hour. The temperature at 6:00 PM = _____ degrees. - Tourist 14291
If a tourist reduced his speed by 1 km/h, he would walk less than 12 km in 3 hours. If he added to the step by 1km/h, he would walk more than 25 km in 5 hours. How fast is the tourist? - Before 14221
Peter and Eve read the same book. Petra read 14 pages a day, so she read it a day before Eva, who read 12 pages a day. How many pages did the book have? - Baking muffins
Aunt Polly is baking muffins at a speed of 4 muffins per minute. Tom comes into the kitchen when Aunt Polly has 12 muffins and begins to eat these muffins at a speed of 6 muffins per minute. When he finally leaves the kitchen, there are four muffins at th - Bratislava 14143
At 8:00 a.m., an express train left Bratislava for Poprad, which was 340 km away. At the same time, an express train left Poprad for Bratislava. The express train to Bratislava went at a speed of 80 km/h, and the express train to Poprad went at a speed of - Cyclists 13831
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? - Doug biked Doug biked 5 1/4 miles in 3/4 of an hour. What is his average speed?
- A filter
It is a pool with a volume of 3500 liters. The filter filters at 4m cubics per hour. How many minutes would it filter the entire pool?
