Hey!

_______________

Maximum speed of the train = 90 km/h
Time taken = 10 hrs
Distance travelled = 500 km

Average speed = Total distance travelled / Total time taken

Avg. speed = 500 / 10

Avg. speed = 50 km/h

Ratio of maximum speed and average speed =

= 90 : 50
= 9 :5

HEY!!

________________________________________

Speed of the train = 90 km /h

Time (t) = 10 hours

Distance travelled by the train = 500km

Speed = $\frac{Distance }{Time}$
Average Speed= $\frac{500}{10}$ = 50 km/hr

Ratio of speed = → 90 : 50 → 9 :5
