HESI A2 Math Practice Test 2023

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: B

Rationale: To convert milliliters to liters, you divide by 1000 since 1 liter is equal to 1000 milliliters. So, 8000 milliliters divided by 1000 equals 8 liters. Therefore, the correct answer is B: 8 liters. Explanation for incorrect choices: A: 0.8 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.8 liters. C: 0.8 liters - Same as choice A, incorrect conversion. D: 0.08 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.08 liters.

Correct Answer: A

Rationale: To add fractions, we need a common denominator, which for 3, 6, and 5 is 30. So, we rewrite the fractions with a denominator of 30: 20/30 + 5/30 + 12/30 = 37/30. Simplifying 37/30 as 1 & 7/30 gives us the correct answer, choice A. The other choices are incorrect because they do not reflect the accurate sum of the fractions. Choice B is incorrect as it simplifies to 1 & 1/15, not 1 & 7/30. Choice C simplifies to 2/5, which is not the sum of the given fractions. Choice D simplifies to 3/4, which is also not the sum of the fractions provided.

Correct Answer: C

Rationale: To calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 60 mph and time is 5 hours, we get Distance = 60 mph x 5 hours = 300 miles. Therefore, the correct answer is C. Option A is incorrect as it miscalculates the product of 60 x 5. Option B is incorrect as it is a lower value. Option D is a duplicate of option A and is also incorrect.

Correct Answer: A

Rationale: To find 25% of 200, you multiply 200 by 0.25 (25% is equivalent to 0.25). So, 200 x 0.25 = 50. Therefore, the correct answer is A: 50. Choices B, C, and D are incorrect because: B: 60 - This is not correct as 25% of 200 is 50, not 60. C: 25 - This is incorrect as 25% of 200 is 50, not 25. D: 30 - This is also incorrect as 25% of 200 is 50, not 30.
