The east-west streets and north-south avenues of a certain city are numbered consecutively from south to north and east to west. All blocks are squares with the same side lengths. Mandy is standing on the corner of 56th Street and 12th Avenue. Mark is standing on the corner of 32nd Street and 18th Avenue. Mark calls Mandy and asks her to meet him at a spot halfway between their current locations. a. Use the Midpoint Formula to find out where Mark wants to meet. Show your work.
(I did this one, it is (44,15) and don't know the other 2 questions)

b. Mandy says that Mark walks faster than she does, so he should have to walk farther. Assume that Mark walks 1.25 times as fast as Mandy. If Mandy's distance walked in a given time period is d, what is the distance Mark can walk in the same time period?

c. Use your results in part b to write and solve an equation to find the distances Mark and Mandy should each walk.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
