You can calculate the speed of an object by dividing the distance covered by time. Galileo is credited as being the first to measure speed by considering the distance covered by the time it takes. Speed is how fast an object is moving Any combination of unites for distance and time that are useful and convenient are legitimate for describing speed. Some units that describe speed are miles per hour (mi/h) and kilometers per hour. The slash symbol (/) is read as “ per ”. The speed of an object at any instant is called the instantaneous speed. The average speed of an object is the total distance covered by the time. Average speed does not indicate variations in the speed that amy take place during the trip. A simple rearrangement of the definition of average speed gives the total distance covered : total distance covered= average speed X travel time 4.Define speed: ___________________________________________ 5.Complete the following equation: speed= distance/_______________________ 6.How is the slash symbol read in km/h? ______________________ 7.Circle the letter of the sentences that are true of instantaneous speed. a.Instantaneous speed is the total distance covered divided by time. b.Instantaneous speed is the speed at any instant. c.The speedometer on a car shows the instantaneous speed. d.If you traveled 30 kilometers in 1 hour, your instantaneous speed would be 10 km/h.
