As your post is written,  it literally means that new,  increased speed of the bus is  10  km/h,

which is not realistic and which I do not believe, at all.



I am more than convinced that you were going to say something different  
(and even have a guess about it),  but do not want to outstrip your thoughts.

By the way,  when  I  point you on deficiencies in your post,  you should not resent.

The good style  (the only one acceptable style (!) )  is to express your  "THANKS"  to me for pointing your error/errors

or the error/errors of your professor/teacher.


Because I work  ON  YOUR  SIDE  and  FOR  YOUR  BENEFITS.


It is what I really expect.

Using the description as written, trip distance 300 km, unknown bus trip speed r
                        SPEED         TIME         DISTANCE

Trip taken                  r           300/r         300

If this higher speed        10         300/10=30      300

Difference                               1

300%2Fr-30=1, time difference equation
300%2Fr=31
r=300%2F31
r=9%2621%2F31----------bus speed used for the trip, not much different than the one taken. This is a very slow trip. Maybe recheck your problem description.
