Here is the problem: If you are driving 58 mph, how long would it take you to go 32 miles. I came up with 33.1 minutes. Wife's practice test answer says 40. Idiots. |

They're just using 0bama math.

When it doubt, just cancel units out. Example - You're trying to find time, so you need to divide miles by miles/hour to arrive at hours. 32 mi/58 mi/hr * 60min/hr = Answer Quick fix, convert to minutes Fixed it a little better. Remember, units must always cancel out.  (leavin you with nothing but the correct unit for the answer). You can solve problems you don't even know how to solve like that.

Is it one of those questions that asks you to pick the closest answer? Like the answers are 20 minutes, 40 minutes, 45 minutes, and 58 minutes? For some tests, questions can be more about the instructions then the answers. |

There is no way to arrive at any other answer, for the stated parameters, (and then put that wrong answer in a book) that does not include debilitating idiocy. Read like 58 mph is a typo and the speed in the question was supposed to be 48 mph. Bingo. __________________________________________________________________ Cross-platform gun database/electronic bound book (v1.3.2) (and the original thread).
