Hi Bhargav, we have corrected the question. Thanks for your feedback.

Hi
Boston lies between Frankfurt and India. So the total distance is the distance between Frankfurt and Boston and that between Boston and India
Hope that helps.

Hii Nilay,
It is given that X waited for 2 hours in Boston and left Boston at noon i.e 12 PM. From this we can infer that he must have reached Boston at 10 AM.

Hi,
time zone is given for each place and hence it can be inferred that if at 6 pm journey has started from F and it Reaches B 2hr before Noon means In B it is 10 am but it is 4hr more than F hence in F it will be 6 am so total time according F time zone is 12 hr travelled between F and B same can be deduce for B and India.
hope it helps!

Hi sweena,
The question says "If his journey, including stoppage, is covered at an average speed of 180 mph"
They have given the average speed
i.e. he has speed of 0mph for 3 hours and about 200mph for 22 hours..
Hence, we consider the stoppage time too
Hope this clarifies:)

"Plane leaves exactly at noon after waiting for 2 hours at Boston" It means plane must have reached Boston at 10 AM of Boston time, waited 2 hours and left at 12 PM. That means 6 am in Frankfurt.
Times of leaving/departure are local to the origin/destination in such problems.

Both are one and the same for all practical purposes.
