man had a basket containing fifty potatoes.
He proposed to his son, as a little recreation, that he should place
these potatoes on the ground in a straight line.
The distance between the first and second potatoes was to be one yard,
between the second and third three yards, between the third and fourth
five yards, between the fourth and fifth seven yards, and so
on—an increase of two yards for every successive potato laid
Then the boy was to pick them up and put them in the basket one at a
time, the basket being placed beside the first potato.
How far would the boy have to travel to accomplish the feat of picking
them all up?
We will not consider the journey involved in placing the potatoes, so
that he starts from the basket with them all laid out.
