HESI A2 Math Questions

Question 1 of 5

A runner leaves at 7:45 for a morning run at an average speed of 6 mph and returns at 10:00. How many miles did he run?

Correct Answer: D

Rationale: The runner ran for 2 hours and 15 minutes (10:00 - 7:45). Distance = speed x time, so distance = 6 mph x 2.25 hours = 13.5 miles. The correct answer is D: 13.5 miles. Summary: A: 11.5 miles - Incorrect, less than the correct answer. B: 14.5 miles - Incorrect, more than the correct answer. C: 12 miles - Incorrect, less than the correct answer.

Question 2 of 5

Which number is the highest among 0.077, 0.777, 0.08, and 0.87?

Correct Answer: D

Rationale: The correct answer is D (0.87) because it is the highest number among the options provided. To compare the numbers, we look at the tenths place first. In this case, 0.87 has the highest value in the tenths place, making it the largest number. The other choices, 0.077, 0.777, and 0.08 have lower values in the tenths place, hence they are not as high as 0.87. Therefore, 0.87 is the correct answer as it is the highest number among the given choices.

Question 3 of 5

If a recipe calls for 2 cups of sugar and you want to make half of the recipe, how many cups of sugar do you need?

Correct Answer: A

Rationale: To make half of the recipe, you need to divide the original amount of sugar by 2. 2 cups of sugar divided by 2 equals 1 cup. Therefore, the correct answer is A: 1 cup. Choice B (1.5 cups) is incorrect because it is not half of 2 cups. Choice C (2 cups) is the original amount and not for making half the recipe. Choice D (0.5 cups) is also incorrect as it is not the correct amount for half of the original recipe.

Question 4 of 5

Leslie is blowing up her favorite photograph. If the photo's original height was 15 inches and the new height is 4 feet, how many feet must the new width be?

Correct Answer: A

Rationale: To find the new width, we need to use the concept of proportionality. Since the height is increasing from 15 inches to 4 feet (48 inches), we set up the proportion: 15/width = 48/new width. Solving for the new width, we get width = (15 * new width) / 48. Given the new height is 4 feet, we substitute 48 for the new height: width = (15 * new width) / 48 = (15 * new width) / 48 = 4.2 feet. Therefore, the correct answer is A: 2.1 feet. Choices B, C, and D are incorrect as they do not align with the proportionality calculation.

Question 5 of 5

A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

Correct Answer: B

Rationale: The correct answer is B (6:00 PM). Taking the medication 12 hours apart from the first dose at 8:00 AM ensures it's evenly spaced throughout the day. 6:00 PM is the most convenient time as it allows for the second dose without disrupting sleep, as it falls after dinner but before bedtime. Choice A (4:00 PM) is too early, which may lead to missing the second dose during the evening. Choices C (8:00 PM) and D (10:00 PM) are too late and might interfere with sleep if taken too close to bedtime. Thus, B is the best option for maintaining the medication schedule effectively.
