Answer:
350km
Let say starting point is 0 N , 0 E
truck driver travels 200 km east from Delhi to Moradabad
hence at mordabad his position is 0 N , 200 km E
Then, he travels 80 km each day eastwards for the next 5 days and arrives at Kathmandu,
= Travelled = 50 x 80 = 400 km East
So,
Position at kathmandu = 0N, 200 + 400 km East
= 0N, 600 km East
From Kathmandu, he drives 350 km west to Bareilly,
= 350 km west = - 350 km East
So,
Position at Bareilly = 0N , 600 - 350 km East
= 0 N , 250 km East
Starting point = 0N , 0E
Ending point = 0N , 350 km
Distance = 350 km
He is 350 km far from his starting point.
