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
