A passenger train running at the speed of 100 kms/hr leaves the railway station 8 hours after a goods train leaves and overtakes it in 6 hours. What is the speed of the goods train?
1). 32.86 kms/hr
2). 32.22 kms/hr
3). 42.86 kms/hr
4). 42.22 kms/hr
Let the speed of Good’s train be y km/hr
Distance travelled by it in 8 hours = 8y km
Relative Speed = 100 – y km/hr
Since passenger trains overtakes goods train in 6 hours
So, 8y = 6 × (100 – y)
14y = 600
y = 42.86 km/hr
