36 kmph.
As the Passenger Train will cover 360 km in 4 hours at the speed of 90 kmph so the Goods Train will cover 360 km in 6 hours + 4 hours = 10 hours.
so the Goods Train is at the speed of 36 kmph (360 km/10 hours).
As the Passenger Train will cover 360 km in 4 hours at the speed of 90 kmph so the Goods Train will cover 360 km in 6 hours + 4 hours = 10 hours.
so the Goods Train is at the speed of 36 kmph (360 km/10 hours).
