Notation: ( x , y ) where x is the time passed after noon and y is the mile marker
"At exactly noon you pass mile marker 50 in your car"
( 0 , 50 )
"At 230 pm you pull into a rest stop at mile marker 215"
( 2.5 , 215 )
"What was your average speed during this time?" Average speed = (change in y) / (change in x) = ( 215 miles - 50 miles ) / ( 2.5 hours - 0 hours)
= ( 165 miles ) / ( 2.5 hours ) = 66 miles per hour (mph)
