The cost of a protein bar increased from $2.50 to $2.80. The percent increase in the $2.80 rate was how much?
Correct Answer
B. 12%
Explanation
The percent increase can be calculated by finding the difference between the new price and the original price, dividing it by the original price, and then multiplying by 100. In this case, the difference is $0.30 ($2.80 - $2.50), and the original price is $2.50. Dividing $0.30 by $2.50 gives 0.12, which when multiplied by 100 gives 12%. Therefore, the percent increase in the $2.80 rate is 12%.

An aircraft flies over Boondock Air Force Base at 10:20 a.m. At 10:32 a.m., the plane passes over Sea Side Naval Air Station, 120 miles away. How fast is the aircraft traveling?
Correct Answer
B. 600 mpH
Explanation
The aircraft travels from Boondock Air Force Base to Sea Side Naval Air Station in 12 minutes (10:32 a.m. - 10:20 a.m.). The distance between the two locations is 120 miles. To find the speed, we divide the distance by the time taken: 120 miles / 12 minutes = 10 miles per minute. To convert this to miles per hour, we multiply by 60 (since there are 60 minutes in an hour): 10 miles/minute * 60 minutes/hour = 600 miles per hour. Therefore, the aircraft is traveling at a speed of 600 mph.

After a series of well–publicized failures by various inventors, Orville and Wilbur Wright succeeded in flying and controlling a heavier–than–air craft on December 17, 1903. The War Department, stung by its investment in a failed effort by Samuel Langley and compounded by the Wright’s own secretiveness, initially rejected the brothers’ overtures toward the government to buy the aircraft. Prevailing sentiments held that the immediate future still belonged to the balloon. In August 1908, the two brothers delivered the first Army aircraft to the U.S. Government. That the U.S. government managed to purchase an airplane was a minor miracle. For more than four years after the Wright brothers’ successful flight at Kitty Hawk, North Carolina, the government refused to accept the fact that man had flown in a heavier-than-air machine.
Which of the following statements is not supported by the above passage?
