Question

the maximum speed of a train is 80 km per hour it takes 10 hours to cover a distance of 400 km find the ratio its maximum speed to its average speed

Answer 1

Hi..

The train's maximum speed= 80 km/hr
Average speed = total distance travelled
                          total time taken
The train's average speed= 400km            =  40km/hr
                                         10 hours

ratio of maximum speed to average speed= maximum speed : average speed
                                                                     80km/hr : 40km/hr
                                                                          =   2:1



Hope this helps u!!
