please give me right answer a passenger train running at a speed of 80 kilometre per hour leaves at railway station 6 hours after   a goods train leaves at overtakes it in 4 hours what is the speed of the goods trains

Given passenger train is running at a speed of 80 km/hr

So distance covered in 4 hrs will be 80 x 4 = 320 km

Now in 10 hours distance covered by goods train will be 320 km

Therefore speed of goods train will be 320 / 10

                                                             = 32 km/hr

OR

Let speed of goods train  be x km / hr

So speed of passenger train is 80 km/hr

Goods train travels in 6 hrs and passenger train overtakes by 4 hours.

So it will be 10 x km and 80 x 4 km

So 10 x = 320

Or x = 32 km/hr
