There are two cars. One is 60 miles north of the other. Simultaneously, the car to the north is driven westward at 15 miles per hour and the other car is driven eastward at 25 miles per hour. How many miles apart are the cars after 2 hours?	Answers
A) 60  B) 80  C) 100  D) 120  E) 140
Here, drawing a quick sketch of the 'actions' described will end in a diagonal line that you canbuilda right triangle around:   The right triangle will have a base of 60 and a height of 80. The hidden pattern here is a 3/4/5 right triangle (the 60 lines up with the '3' and the 80 lines up with the '4'). In this way, you can deduce that each side is '20 times' bigger than it's corresponding side:   3/4/5 becomes   60/80/100   Thus the distance between the two cars is the length of the hypotenuse of this larger right triangle...   Final Answer: 100
