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 ?
"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 : c"
sqrt(add(power(add(multiply(25, 2), multiply(15, 2)), const_2), power(multiply(25, 2), const_2)))
