Question

the maximum speed of a train is 80 kilometre per hour it takes 10 hours to cover a distance of 400 km find the maximum speed of Earth's average speed ​

Answer 1

Answer:

The train's maximum speed= 80 km/hr

Average speed = total distance travelled

                          total time taken

The train's average speed= 400k   

=  40km/h. 10 hours

ratio of maximum speed to average speed= maximum speed : average speed

80km/hr : 40km/hr

                                                                            

=    2:1
