Question

At the start of the trip the speedometer of a car read 8000km and 8350km at the end. Which takes 3hr calculate the average speed of a car in km /hr and m /s

Answer:

Initial reading , d1 = 8000 km

Final reading , d2 = 8350 km

So , Distance = d2 - d1 = 8350 - 8000

=> Total Distance = 350 km

Time = 3 h

Now Average speed is Total distance traveled in total time

Average Speed = 350 / 3

=> Average Speed = 116.67 km/h

=> Average Speed = 116.67 *5/18 = 32.408 m/s
