fraction of distance covered by train = 3/8
fraction of distance covered by taxi = 2/5
fraction of distance covered by walking is
He walked = 3 1/2 km = 7/2 km
So 9/40 fraction of total journey = 7/2 km
then total journey will be
Distance covered by taxi will be
Distance covered by taxi is 6 2/9 km
fraction of distance covered by taxi = 2/5
fraction of distance covered by walking is
He walked = 3 1/2 km = 7/2 km
So 9/40 fraction of total journey = 7/2 km
then total journey will be
Distance covered by taxi will be
Distance covered by taxi is 6 2/9 km

Let the total journey distance be 'x'.
Distance covered by train = (3x/8).
Distance covered by Taxi = (2x/5).
Now,
Journey covered in train and taxi:
= > (3x/8 + 2x/5)
= > (15x + 16x)/30
= > 31x/40.
Given that he walks the rest of the distance. He walks 7/2 km.
= > x - (31x/40) = 7/2
= > (40x - 31x)/40 = (7/2)
= > 9x/40 = (7/2)
= > 18x = 280
= > x = 280/18
= > x = 140/9.
Hence,
Distance covered by taxi = (2/5) * (140/9)
= > 56/9
= > 6 2/9 km.
Hope this helps!
