Answer 1

Answer:

The given question is solved in the uploaded photos.

Note that here,in the question , it is assumed that speed and velocity are same thing(though actually,they are not), we don't have to think for it.

In the second part of the question,we have to just find total time (we don't have to think for equal time or other things) so that we can finally,get the average speed.
