Question

A train covers 108 km in the first two hours,36 km in the next half an hour and 90 km in the next one and half hour.Find the average speed of train during the whole journey?

Answer 1

Total distance=108+36+90=234km
Total time=2h+0.5h+1.5h=4h
Average speed = total distance/total time
=234/4
=58.5km/h

So, 58.5km/h is ur answer.

Plz mark as brainliest:-) :-)

Answer 2

Average speed = Total Distance Covered / Total Time Taken
since total distance covered = 108km+36km+90km=234km
And total time taken=2hr+1/2hr+1½hr=4hr.
Therefore average speed = 234km/4hr
=58.5km/hr
