Thank you We sneak Sandra is grandmother nannette who lives

00:07

on the eastern coast of maine wants to visit her

00:10

granddaughter who lives on the western coast of oregon Unfortunately

00:14

she doesn't like flying because she has an irrational fear

00:16

of flying into a volcano and she won't travel by

00:19

train because she read one too many agatha christie novels

00:22

So she hops in her car and heads west Well

00:25

here's the problem She drives a twenty two miles an

00:27

hour so yeah it's going to take her a while

00:29

At the end of every day she calls to check

00:31

in with sander over the phone and let her know

00:32

what negligible progress she's made Well then it's starting to

00:36

get depressed because at the rate she's travelling driving for

00:39

twelve hours a day it's going to take her weeks

00:42

to get to oregon and who knows how many weeks

00:45

you know she's got left No wonder she's feeling down

00:48

So sander comes up with an idea she's going to

00:50

use what she's learned about derived units to convert her

00:53

grandmother's snail like pace into something more encouraging Instead of

00:57

looking at her rate in terms of miles per hour

01:00

she wants to express it in terms of meters per

01:02

day that should help the old broad buck up a

01:05

bit By using her conversion chart sander determines that there

01:08

are point zero zero zero six two miles in a

01:11

meter Now here's the tricky part She wants to convert

01:14

hours today's But grammy is only driving twelve hours a

01:18

day So sandor has to set up our equation this

01:20

way Twenty two miles over one hour times one meter

01:23

over point oo six two miles times twelve hours over

01:28

one day well crunching the Numbers she gets 260 four

01:31

over point hello six to which comes out to four

01:34

hundred twenty five thousand eight hundred six point five Well

01:37

the miles canceling the hours cancel in Sanders left with

01:39

meters per day exactly what she was looking for Well

01:42

the next time she and then add chat on the

01:44

phone sandra tells her to stop thinking about her progress

01:46

as twenty two miles an hour and instead think about

01:49

it It's four hundred twenty five thousand eight hundred six

01:51

and a half meters a day Well sure enough that

01:53

does the trick And and that is newly energized To

01:56

be fair it might Also have been something to do

01:58

with the half dozen red bulls she pounded this morning
