Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by the department of public health

00:07

which gives this problem a solid b rating All right

00:11

we'll check out this day Lucious drew a scale map

00:14

of his home his work place and his favorite restaurant

00:17

on a napkin on the napkin The distance between his

00:20

home his work place is seven centimeters and the distance

00:23

between his home and his favorite restaurant is two centimeters

00:27

The actual distance between his home and his work place

00:30

is thirty five kilometres All right lucious favorite restaurant is

00:36

how many kilometers from his home huh All right Here

00:41

the potential answer All right so what's this question asking

00:46

well were given a pretty little diagram Here was a

00:48

short paragraph of explanation and we need to use all

00:51

that stuff to determine how far lucious has to travel

00:54

from home to get his weekly sushi fixed All right

00:57

well let's break down the information we're given First we're

01:00

told that this drawing is to scale which doesn't mean

01:04

lucious home is actually seven centimeters from work Too bad

01:07

because that would be one heck of a commute but

01:10

it does mean that there is a direct correlation between

01:13

the itty bitty distances on a napkin app and the

01:16

real life distances they represent were given that the actual

01:20

distance from lucious home to work is thirty five kilometres

01:23

Well that's represented by seven centimetres on the napkin then

01:27

seven centimeters in napkin land equals thirty five kilometres Well

01:33

you simplify that a bit further and we divide both

01:35

sides by seven and it gets us that one centimeter

01:38

in napkin land equals five kilometers Okay so now because

01:42

we know the entire drawing is scale we can apply

01:45

that same ratio to the distance between lucious home and

01:48

favorite restaurant Well it's two centimeters on the map and

01:52

if one centimeter equals five kilometers well than in real

01:56

life the restaurant must be twice that or ten kilometers

01:59

from age's Home of answer is that and we don't

02:03

know how much longer it's going to be his favorite

02:05

restaurant because they've been getting pretty upset with him for 00:02:08.07 --> [endTime] stealing all their little cocktail napkin
