Conversions of a velocity unit in word problems

• Motion on circle
  The bend has a radius of r = 100 m and is inclined at an angle of 20° to the horizontal plane (= tilt angle). What is the safe (the "best") speed to go through this curve? Sketch the picture regarding NIVS, mark the forces, and calculate.
• Tourist route time
  How long would a tourist walk the route if he measured 24.9 cm on a map with a scale of 1:25000? The marching speed is 4 km/h.
• Stair climbing performance
  A person weighing 50 kg can climb 15 stairs. One step is 18 cm high. Determine a person's performance when: a) slowly climbing the stairs if it took him 13 seconds b) going down the stairs slowly if it took him 10 seconds c) quickly climbing the stairs if
• Acceleration of a train
  The train passes 700 m, braking with an acceleration of -0.15 m/s². How long does it break, and what is the final speed of the train if the initial was 55 km/h?
• Police on time
  A boat carrying smugglers has left the shore and is travelling at 85 km/h. After 10 minutes, a police boat starts chasing it at 110 km/h. International waters, where the possibility of apprehending the smugglers ends, begin 30 km from the coast. Will the
• Diesel tank filling
  The diesel tank has a volume of 19.6 hl. The inflow oven, which flows 17.5 l per minute, was opened for 1.5 hours. How long does the inlet pipe need to be opened for the tank to be completely filled?
• Wave travel time
  A plane wave has an amplitude u0 = 40 cm and a frequency f = 10 Hz. The speed of wave propagation through the medium is v = 40 cm/s. At a distance x = 10 cm from the starting point, the wave has an instantaneous deflection u = 15 cm. How long does it take
• Race car loss
  Two race cars passed the finish line at a speed of 216 km/h at a distance of 0.003 s. Express the loss of the second in centimeters.
• Friction coefficient
  What is the weight of a car when it moves on a horizontal road at a speed of v = 50 km/h at engine power P = 7 kW? The friction coefficient is 0.07
• Train speed
  The troop fired two guns from the same place at 10 minutes and 30 seconds intervals, but a person on a train approaching the place heard a second shot 10 minutes after the first. The speed of the train (in km/hr), supposing that sound travels at 340 m/s,
• Plane meeting
  The distance between the two airports is 3480 km. There are regular connections from airport 1. The plane takes off at 6:30 am at an average speed of 600 km/h. From airport two at 7:00 am at a speed of 540 km/h. When will they meet?
• Bus distance
  If the bus runs 5 km in 8 minutes, how many kilometers will it drive in three-quarters of an hour at a constant speed?
• Aircraft nose down
  How long will an airliner fall from a height of 10000 m at a speed of 1,000 km/h?
• Knight
  Knight passed 36 km long track in 144 minutes. What was his average speed?
• Against each other
  Two cars start simultaneously from points A and B, which are 29 km apart, and travel toward each other at speeds of 82 km/h and 72 km/h. How long until they meet, and what distance does each car travel?
