Propositiones ad Acuendos Juvenes/Problems/1 - De Limace

by : Problem $1$

 * De Limace: A Slug
 * A leech invited a slug for lunch a leuca away.
 * But he could only walk an inch a day.
 * How many days will he have to walk for his meal?

Solution

 * $90 \, 000$ days, or $246$ years and $210$ days.

(This does not take into account leap years, as it assumes a year of strictly $365$ days.)

Proof
It is understood that there are:
 * $1500$ paces to a leuca
 * $60$ inches to a pace.

Hence there are $90 \, 000$ inches to a leuca.

Thus at $1$ inch per day, it will take the slug $90 \, 000$ days to arrive for his meal.
