Given: Ramesh travelled 1200 km by air which formed
2
3
of his trip. One-third of the remaining trip he travelled by car And the rest of the journey he performed by train. Formula Used: Distance = Speed × Time Calculation: Let the total distance to travel be ‘a’. According to the question
2a
3
=1200 ⇒ a = 1800 km Again, According to the question ⇒ Distance travelled by car =
1
3
×(1800–1200)=200 km ⇒ Distance travelled by train = 1800 – 1200 – 200 = 400 km ∴ None of the answers match, answer is d.
