Answer:
The speed of train is 36 km/h or 45 km/h.
GIVEN:
TOTAL DISTANCE COVERED 180 km/h
TO DETERMINE:
The speed of train
Step-by-step instructions:
Let the speed of the train is x km/h.
Speed after increase by 9 km/h is (x+9) km/h.
From the given condition
180/x - 180/(x+9) = 1 [ As time= distance/speed]
Simplifying we get x² + 9x - 180×9 = 0
We get x= 36 & 45.
