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

00:06

jour brought to you by cloth napkins the fancy way

00:09

tio white thousand island dressing off your chin All right

00:13

here we go Check out Staggering Lucious drew a scale

00:16

map of his home his work place and favorite restaurant

00:19

on a napkin on the napkin The distance between his

00:22

home and his work place is seven centimeters and the

00:24

distance from his home in his favorite restaurant is two

00:27

centimeters The actual distance between his home His work place

00:30

is thirty five kilometres lucious khun drive from home and

00:34

an average speed of forty miles an hour to both

00:36

his workplace and to his favorite restaurant In the time

00:40

it takes him to get to work is how many

00:43

times the time it takes him to get to his

00:44

favorite restaurant All right so we're not quite done with

00:50

lucious We need to figure out how many times longer

00:53

take solutions to get to work then to his favorite

00:55

restaurant All right so we've got another drop down with

00:59

three options Five three point five and seven We're told

01:05

that lucious can drive home at an average of forty

01:08

miles an hour but we can just throw that information

01:11

out the window Careful check for pedestrians That part is

01:16

just a red herring and it's something they throw in

01:18

there to confuse you It doesn't matter how fast lucious

01:22

is traveling he could be going the speed of light

01:24

for all weekend All that matters is how much longer

01:28

it takes him to get tau one place rather than

01:31

another And if he's moving at a constant speed than

01:34

his exact paces well beside the point if we check

01:38

out those distances again we can see that work is

01:41

seven centimeters from home on the map or thirty five

01:44

kilometres in real life and the restaurant is two centimeters

01:47

from home on the map or ten kilometers in real

01:50

life Well either way it's a seven to two ratio

01:53

so it takes lucious seven halves as long to get

01:56

to work Or if we want to say that in

01:58

english we can take seven divided by two to get

02:00

three point five So it takes lucious three point five

02:04

times as long to get to work as it takes

02:06

him to get to the restaurant and that's our final

02:08

answer over his bosses and buying that as the reason

02:12

he's been working remotely from home last Month low shows 00:02:17.32 --> [endTime] You'll follow me wherever i go
