Answer:
x= 25. So, the train will cover a distance of 25 km in 20 minutes. or y = 250 × 60 75 = 200 minutes or 3 hours 20 minutes. Therefore, 3 hours 20 minutes will be required to cover a distance of 250 kilometres.

It is given that the uniform speed of the train is 80km/hour
.
We will use the unitary method now.
Distance covered by the train in 1 hour =80km
We can write the same statement as
Distance covered by the train in 60 minutes =80km
Distance covered by the train in 1 minute =80km/60minuted
We have to find the distance covered in 30 minute.
Using unitary method, we get
Distance covered by the train in 30 minute =
.80/60×30==40km
