we go If a squirrel can very nine nuts in

00:09

two hours than how many nuts can the squirrel berry

00:13

in x plus two hours assume the squirrel works at

00:16

a constant rate The squirrel buries nuts at a rate

00:22

of nine pert two hours or four and a half

00:26

an hour right We can assume the squirrels not burying

00:28

takes place at a constant rate So in half that

00:31

amount of time yeah one hour we get that nine

00:33

halves If you want to be all fancy about it

00:35

to find the equation then for how many nuts the

00:38

squirrel can bury in x plus two hours But we

00:42

just multiply this expression by the rate of nuts buried

00:44

per hour That gets us nine half times the quantity

00:47

x plus two which is nine Acts over 2 plus

00:51

9 halves times too which is ah nine x over

00:55

two plus nine That's it That's pretty good rates world
