Question 1171355: Hi. Town P and town Q were 720km apart. Maggie and Anne left town P at the same time. The average speed of Anne was 40km per hour while Maggie was 60km per hour. As soon as they passed point K which was 1/3 of the total distance, Maggie began to travel at 80km per hour. Both of them took the same number of hours to travel from P to Q.
How long did Maggie take to travel from P to Q.
What was Annie's average speed from point K to town Q.
Thanks

You can put this solution on YOUR website! .
This problem is BADLY POSED.
Notice that they passed the point K at DIFFERENT TIME MOMENTS.
Hence, at which PRECISELY of these TWO time moments Maggie increased her speed ?
Second notice is CONCEPTUAL/editorial.
When you say "Maggie and Anne left town P at the same time",
you SHOULD, actually, say "Maggie and Anne left town P at the same time moving to Q".
Hello, it is Math: here EVERY WORD does MATTER,
should be used correctly and with right connections (logical and grammar) with the other words.
Please do not respond me that it is how it is written in your textbook or written by your professor.
These arguments do not work and I will not accept them.
As the post is worded, printed and presented, it is not a Math problem and no one peer-reviewed textbook will print it.
The only acceptable response is to post me your "THANKS" for pointing your errors.
------------
Comment from student : I do apologies for my error. Thank for pointing it out. Will resend with corrections
My response : Good answer. I accept it.
