Let the distance by train be'x'.
so, distance covered by bus=2x
Whole journey =70 km
10+2x+ x=70
10+3x=70
` 3x=70-10
3x=60
x=60/3
x=20 km
The distance travelled by
train=x=20km
bus=2x=2 (20)
=40 km
so, distance covered by bus=2x
Whole journey =70 km
10+2x+ x=70
10+3x=70
` 3x=70-10
3x=60
x=60/3
x=20 km
The distance travelled by
train=x=20km
bus=2x=2 (20)
=40 km
