Question

Johnson travelled 3000 km by air which formed 2/5 of his trip. One third of the whole trip, he travelled by car and the rest of the journey he performed by train. What was the distance travelled by train?

Answer 1

Answer:

total distance travelled by johnson =3000 km

he travels 2/5 of his trip by air =2/5×3000=1200 km by air

now he travels 1/3 of trip by car =1/3×3000=1000 km by car

now by train

total trip distance - distance travelled by car + by air

3000 - 1000 + 1200

=800 km by train
