Question

the odometer rates 4000 km at the start of the trip and 2500 kilometre at the end of the trip the trip took 2 hours calculate average speed in the car kilometres per hour metres per hour

Answer 1

We know that Speed = Distance/Time

                                    = 4000 - 2500/2

                                    = 1500/2

                                    = 750 km/hr.

  
We know that 1km/hr = 1000m/hour

                        750km/hr = 750000m/hr.



Now,

750km/hr = 750 * 5/18

                  = 208.333 m/s.





Hope this helps!
