Atrain runs for 3 hours at a speed of 55 km per hour and for the next 2 hours at a speed of 65 km per hour. find the average speed of the train for the 5 hours journey.

Total time taken =3+2 =5 hrs

Distance travelled in 3hrs at an average speed of 55hrs=Speed×Time=55×3=165km

Distance travelled in 3hrs at an average speed of 55hrs=Speed×Time=55×3=165km

Distance travelled in 2hrs at an average speed of 65km/hr=65×2=130

Distance travelled in 2hrs at an average speed of 65km/hr = 65×2=130

Total Distance=165+130=295

Total Distance= 165+130=295

Average speed = DistanceTime
=295×5=59km/hr
