A. The distance moved by the car is 15 Km

B. The speed (in Km/min) of the car during the time is 0.75 Km/min

C. The speed (in Km/h) of the car during the time is 45 Km/h

A. How to determine the distance

  • Initial reading = 57321.0 km
  • Final reading = 57336.0 km
  • Distance =?

Distance = Final reading – Initial reading

Distance = 57336.0 – 57321.0

Distance = 15 Km

B. How to determine the speed (in Km/min)

  • Distance = 15 Km
  • Initial time = 8:30 am
  • Final time = 8:50 am
  • Time = 8:50 – 8:30 = 20 mins
  • Speed =?

Speed = distance / time

Speed = 15 / 20

Speed = 0.75 Km/min

C. How to determine the speed (in Km/h)  

  • Distance = 15 Km
  • Time = 20 mins = 20 / 60 = 0.33 h
  • Speed =?

Speed = distance / time

Speed = 15 / 0.33

Speed = 45 Km/h
