----
Let the cars be "n" and "e":
---
The travel for 2 hrs.
n goes 2*30 = 60 miles
---
e goes 2*40 = 80 miles
----
Use Pythagoras to find the distance between at 4:00PM
-------
d = sqrt[60^2+80^2]
---
d = sqrt[3600 + 6400]
---
d = sqrt(1000)
d = 10*sqrt(10) miles

One car is 60 miles away, the other is 80 miles away.
It's a right triangle.
Use Pythagoras
d = 100 miles
