jour brought to you by the department of public health

- 00:11

- 00:14
of his home his work place and his favorite restaurant
Full Transcript
- 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
