Question 1205872
.


As the post is worded and presented, it is expected (or would expected)
that the numerical value of the velocity/speed is given,
which is not the case in this post.


At these circumstances, the meaning of the post/assignment is unclear.



My opinion is that the visitor simply forgot to attach this info due to lack of 
attention or understanding (or BOTH).


Or, alternatively, this post is a copy from an untrusted source.
