You can put this solution on YOUR website! .
The road from A to B is 10km uphill followed by 20km downhill. A motorcyclist averages 36km/h uphill and 90km/h downhill.
Calcilate the average speed from B to A
~~~~~~~~~~~~~~~~~~~~
The steepness uphill from A to B can be TOTALLY different from that from B to A.
Same for steepness downhill from A to B, comparing with that from B to A.
The given data is enough to calculate the average speed from A to B.
Bu it may be TOTALLY different from the average speed from B to A.
We simply HAVE NO necessary data to answer the question in the form, how it is POSED IN THE POST.
-------------------
I clearly understand what you only "copy and paste" and do not think on what is written in your post.
I also clearly understand, that you will refer to your teacher, saying that the problem came from him (ot from her)
exactly in this form.
But, in any case, the person who created this post, must know that the problem is posed
