Avenue, mary calls mandy
ant locations
standing on the corner of 35th street and 21st ave
him at a spot halfway between their current loca
a mark wants to meet, shove
a. use the midpoint formula to find out where
x + x2 yo + 420
39+35 - 15th

(47, 12)
andy walks to him, how far must she walk?
b. if mark stays where he is and mandy walks to him
d=f(x2 - x,)² + (42-4,2
d=1(35-5a)2 + (21-1572
d=51-24)2 + (622
5 576 +36
5612
24.74
so he should have to walk farther to
nes as fast as mandy. if mandy's dista
listance mark can walk in the same time
c. mandy says that mark walks faster than she does, so hech
be "fair". assume that mark walks 1.15 times as fast
walked in a given time period is d, what is the distance
period?
1.15x
d. use your results from part band c to write and solve an equation to find the diston
mark and mandy should each walk so that they each walk a "fair" amount
