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
