Prędkość (dział: prędkość, droga, czas)- Matematyka Szkoła Podstawowa i Gimnazjum

In this video, I show how to calculate speed using the formula that connects distance, time, and speed. I teach how to identify which data in a problem represent distance and which represent time, and I explain how to divide these values to find speed. Through three examples — a car trip, a snail’s movement, and a train journey — I demonstrate step by step how to convert units, simplify fractions, and explain how to convert time given in hours and minutes into a decimal value. I also discuss the case of dividing by a decimal number, illustrating it by transforming the division into one with a whole number. Contents: 1. Calculating the speed of a car based on distance and time 2. Calculating the speed of a snail in cm/min 3. Calculating the speed of a train using the difference between times Find more in the playlist: [   • KALENDARZ PRĘDKOŚĆ DROGA CZAS  ](   • KALENDARZ PRĘDKOŚĆ DROGA CZAS  ) EASY ACCESS to all my math lessons is available on my website: [www.matmagwiazdy.pl](http://www.matmagwiazdy.pl) On this channel, you will find a complete course – 100% of the lessons – in Mathematics for Primary School, High School, and Technical School.
