Two men start from the same corner $A$,
. . going in different directions around a field 1 mile square.
The man going along AB walks 4 mph, and the other man going along AD goes 3 mph.
Where and after how long will they meet?

One man walks at 4 mph, the other at 3 mph.
They have a combined speed of 7 mph.

How long will it take them to walk a total of 4 miles?
. . It will take them: . $\boxed{\frac{4}{7}}$ of an hour.

The first man walks: . $4\times \tfrac{4}{7} \:=\:\tfrac{16}{7} \:=\:2\tfrac{2}{7}$ miles.

The second man walks: . $3 \times \tfrac{4}{7} \:=\:\tfrac{12}{7} \:=\:1 \tfrac{5}{7}$ miles.

They will meet at point $P.$
Code:

A * → → → → * B
