Explanations
1. The short hand is between the 11 and the 12, so it must be between 11:00 and 12:00.
To find the minutes, if the long hand is pointing directly at a number, then multiply that
number times 5. If the long hand is pointing to a tick mark between the numbers,
multiply the number before it by 5, then add 1 for each tick mark past the number.
In this problem, the long hand is pointing to the 11.
11 × 5 = 55
So this clock says the time is 11:55.
2. Since there are 1000 meters in 1 kilometer, divide 30,000 meters by 1000 to convert to
kilometers.
30,000 ÷ 1000 = 30 kilometers
3. Note that inches are along the top of the ruler, and centimeters are along the bottom of
the ruler. The question asks you to measure the nail to the nearest quarter-inch. So,
notice the tick marks for 1/4, 1/2, and 3/4 between each number. Comparing the nail to the
ruler, the nail head is at 0, and the point of the nail is at 1 3/4 inches. So, the length of
the nail is 1 3/4 inches.
4. Each mark on the Celsius side of the thermometer represents 1 degree. In this case, the
mercury level of the thermometer corresponds to -1° Celsius.
5. Since there are 1000 meters in 1 kilometer, multiply 7 kilometers by 1000 to convert to
meters.
7 x 1000 = 7,000 meters
