HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To convert yards to inches, you need to know that 1 yard is equal to 36 inches. Therefore, 1.5 yards is 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Choice B (60 inches) is incorrect because it does not accurately convert 1.5 yards to inches. Choices C (72 inches) and D (84 inches) are also incorrect as they do not reflect the correct conversion.

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.

Correct Answer: A

Rationale: To determine the distance traveled by the train, we use the formula Distance = Speed x Time. Given the speed of 65 mph and time of 1.5 hours, we calculate 65 mph x 1.5 hours = 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Option B, 100 miles, is incorrect as it does not match the calculated result. Options C and D, 98 miles and 95 miles, respectively, are also incorrect as they do not align with the calculated distance based on the given speed and time.

Correct Answer: C

Rationale: To subtract 20.7 from 13.4, we need to borrow since we cannot subtract a larger number from a smaller one. So, borrowing from the tens place, we get 13.4 as 12.14. Then, subtracting 12.14 from 20.7 gives us 8.56. Rounding off to one decimal place, we get 8.6, which is closest to choice C: 7.3. Hence, the correct answer is C. Choice A, 7.1, is incorrect as it is not close to the calculated result. Choices B and D are also incorrect as they are not close to the rounded off result.

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.
