Comprehension Passage
Directions: Read the following passage and answer the given questions.
Day 1: A person covers 200 km along the stream and 150 km against the stream. The difference between the time taken to cover upstream and downstream is 10 hours.
Day 2: The distance covered along the stream is 40 km more than the distance covered against the stream which is equal to the distance covered by a person on day 1 along the stream. He takes 6 hours more to cover upstream than downstream distance.
The speed of stream on day 1 and 2 is 15 kmph and 20 kmph respectively.
If the person travels an additional 100 km downstream on Day 1 with the same speed of the stream and the same speed in still water, what will be the difference between the time taken to cover this additional distance downstream and the time taken to cover the same distance upstream on Day 2?
