Thorn example 5 and it says it looks list of all it looks scarier than it really is it's not that bad it says that Pear Street intersects Cherry Street and Peach Street at their midpoint midpoints is a keyword some going to underline it your home is at Point P you leave your home. It down Cherry Street to Plum Street over Plum Street to Peach Street Peach Street to Parish Street over Pear Street to Cherry Street and then back home up Cherry Street about how many miles do you first of all I don't jog any miles if anything alright my bike but even still sometimes it's a struggle go all the way down Cherry Street Cherry Street to Plum Street  Plum Street to Peach Street Peach Street to Perry Street Pier Street to Cherry and all the way back up  so we underline that word mid what does the word midpoint mean hopefully said that it cuts it in half the struggle though is to equal has for whatever reason you know that a midpoint cut something in half but you don't know that the two sides that are equal so if this part right here is 1.3 then this site over here is 1.3 miles  okay I don't know why this pain is not like it's not pain stylist not agreeing with me right now let's try again this is 1.3  then this so has to be 1.3  opposite of all so true so for Peach Street set the whole thing is 2.25 miles and so a pair of street is at the midpoint I know that I need to cut 2.25 and half which is one point 1 - 5 for each piece one point to 5  and so now to find the total distance she jogged all we have to do is out of all the which is okay that's a huge one let's try that again .3 + 1.3 does she jog the whole distance of Cherry Street  + 1.4 Foot Locker running that's already like almost four miles okay plus one 1 - 5  over to Paris Street looks we didn't find the measure for Pear Street so let's do that really quick street is the segment and it is parallel to Plum Street Plum Street is 1.4 miles  Pear Street is smaller to get smaller we're going to / - 1.4 / - is .7  now we can keep hold on so + .7 Plus we had to go back home so plus another 1.3  and so now take a second out them all up I'm going to use my calculator animal 1.3 + 1.3 + 1.4 + 1.1 - 5 + .7 + 1.3 1.71 - 5 I'm sorry 7.125 she jogs or whoever's jogging can definitely not me jocks about 7.125 miles and now what you were hoping that I wouldn't give you go ahead and take a separate sheet of paper out put your name at the top and we are going to have a quick and very brief vocabulary quiz on your next video so player next video once you're ready
