HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: To calculate speed, use the formula: speed = distance/time. In this case, the car traveled 240 miles in 4 hours. Therefore, speed = 240 miles / 4 hours = 60 mph. Choice B is correct as it represents the calculated speed accurately. Choice A (50 mph) is too low, Choice C (55 mph) is close but not accurate, and Choice D (75 mph) is too high based on the calculation.

Correct Answer: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.

Correct Answer: D

Rationale: To find 70% of 200, you multiply 200 by 0.70 (70%). So, 200 x 0.70 = 140. Therefore, the correct answer is D (140). Choice A (100) and B (100) are incorrect as they do not represent 70% of 200. Choice C (200) is incorrect as it represents the full 100% of 200, not 70%.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

Correct Answer: B

Rationale: The correct answer is B (2.2). To convert pounds to kilograms, you need to divide the weight in pounds by 2.2. This is because 1 pound is approximately equal to 0.454 kilograms. Therefore, by dividing the weight in pounds by 2.2, you are essentially converting pounds to kilograms. Choice A (1.8) is incorrect because it is not the accurate conversion factor for pounds to kilograms. Choice C (2.5) is also incorrect as it is not the standard conversion factor. Choice D (2) is not correct either, as it does not accurately convert pounds to kilograms.
