California High School Exit Exam (CAHSEE)
Mathematics Section

7MG1.1

The California High School Exit Exam -- "CAHSEE". The
Mathematics Section contains 80 multiple choice questions, and the
"Measurement and Geometry" (MG) Strand (subsection) has 17 questions. Of
the 17 questions, less than 50% are on "Measurement", but the approach of
this lesson-quiz is to "hard-calculate" the answer, rather than the less
rigorous approach of "approximating" the answer based on 4 choices. The
instructors writing this lesson want students to be able to apply calculation
techniques to solve the problem -- thus strengthening your math ability!
This lesson conforms to the 7MG1.1 Standards of Comparing weights,
capacities, geometric measures, times, and temperatures within and
between measurement systems.
(e.g., miles per hour to kilometers per hour to
feet per second, and cubic inches to cubic centimeters).

You are traveling
North from LA to San Francisco which is 150 miles. Mileage is
given in miles (mi) and
Kilometers (km). How many km? You may use the
calculator below.

If your answer has decimals, ignore them for now.
How to "round-off" taught later.

Answer:
Type answer in the form of nnn, 3 integers only. No decimal
point. No numbers to the right of the decimal point.

10 Points. There are many ways to convert
miles to km, such as hand calculator, pen-paper multiplication, using the
Windows
Calculator shown here. Type 150 in the bar, press the "*" (multiply
sign - circled in red), then 1.609, and press the <Enter> key.

Or on paper: 150
x 1.609
--------
You could also use Excel by typing
=150*1.609 into a cell.

Or any other number conversion programs found on
the web, with Google, by typing "number conversion"

1.
It is important to develop a "number sense", a sense of proportion.
Km are a bit more that 1.5 times Miles. So do a "range check" when
calculating.

Calculate 150 * 1.609 a 2nd way to verify your answer.
