Let the distance travelled by train be x km.
Therefore, the distance travelled by bus= (285-x)km
According to the question,
x/55 + 285-x/40 = 6
=> (x/55 - x/40) = 6 - 285/40
=> - 3/440 x= - 45/40
=> x= 45×440/ 3×40
=> x=165 km
Therefore, the distance travelled by bus= (285-x)km
According to the question,
x/55 + 285-x/40 = 6
=> (x/55 - x/40) = 6 - 285/40
=> - 3/440 x= - 45/40
=> x= 45×440/ 3×40
=> x=165 km
