You're in luck !  This is gonna be easy.  Listen to this:

On the exam, they're gonna put questions about all that same stuff
that they talked about IN the class all those times !  The exact same
material.  And if they didn't talk about it in class, then it won't be on
the exam !    How cool is that ? !

All that stuff you copied from the board, all those notes you wrote in
your notebook so you'd remember it, all those handouts they gave out
in class, all that homework you did ... THAT's what they'll put on the exam !

It's gonna be all stuff that you seen and heard and studied before.
No surprises.  It'll be a breeze, and you're totally gonna do fine.

A car is making a 40 mi trip. It travels the first half of the total distance 20.0 mi at 18.00 mph and the last half of the tota
sukhopar [10]

Answer: The average speed is 27,24 mph (exactly 1008/37 mph)

Explanation:

This is solved using a three rule: We know the speeds and the distances, what we can obtain from it is the time used. It is done like this:

1h--->18mi

X ---->20 mi, then X=20mi*1h/18mi= 10/9 h=1,111 h

1h--->56mi

X ---->20 mi, then X=20mi*1h/56mi= 5/14 h=0,35714 h

Then the average speed is calculated by taking into account that it was traveled 40mi and the time used was 185/126 h=1,468 h and since speed is distance over time we get the answer. Average speed= 40mi/(185/126 h)=1008/37 mph=27,24 mph.
