Instructions

You may print this sheet, if you wish, but it is not necessary. Please show work carefully and clearly put a box around the final result of your calculation. This means that every conversion factor must be shown and you must show the units that cancel out. Scan your work and submit it as a PDF. Problems are 10 points each. For completing the assessment you earn a 70. The bonus question is worth 5 extra points and it is permitted to earn up to 105.

A rectangle of land has sides of length 200 m and 150 m.
1. What is the area of the land in square meters (m²)?
2. What is the area of the land in square feet (ft²)?
At a speed of 65 mi/hr how many minutes will it take to travel 25 mi?
Show work for the following metric conversions:
1. Convert 0.56 m to mm
2. Convert 475 mg to g

1. Convert 265 cm to m
2. Convert 42 μL to mL
Convert the speed 42 m/s to mi/hr.
Bonus: How far, in miles, does a bullet travel in 2.5 s if it is fired horizontally at 1,000 m/s?

Did you remember to show your work properly? The point of this lesson is not the correct answer, which you could Google anyway. The point is to learn the skill of unit conversion, which is an important one throughout your chemistry course.
