A man covers 215 of the total journey by train, 920 by bus and the remaining 10 km on foot. His total journey (in km) is?

To solve this problem, we first need to understand that the man's total journey is made up of three parts: the distance he travels by train, by bus, and on foot.

1. We know that he travels 10 km on foot.

2. We also know that the distance he travels by train and by bus are given as fractions of the total journey.

3. To find the total journey, we need to express the 10 km as a fraction of the total journey.

4. The fraction of the journey he travels on foot is 1 - (215 + 920) = 1 - 1135 = -135.

5. Therefore, the total journey is 10 km / -135 = -0.074 km.

6. However, distance cannot be negative, so there seems to be a mistake in the problem. The fractions of the journey traveled by train and by bus add up to more than the total journey, which is not possible.

Please check the fractions given for the distances traveled by train and by bus.
