HESI A2 Math Questions
Question 1 of 5
A car travels 60 miles per hour for 2.5 hours. How far does the car travel?
Correct Answer: A
Rationale:
To find the total distance traveled, multiply the speed of the car (60 miles per hour) by the time it traveled (2.5 hours): 60 miles/hour * 2.5 hours = 150 miles.
Therefore, the correct answer is A.
Choices B, C, and D are incorrect as they do not correctly calculate the total distance traveled by the car.
Question 2 of 5
An artist sells paintings at $5.50 each. She has 7 stands and pays $35 per stand. What is her profit if she sells an average of 11 paintings per stand?
Correct Answer: B
Rationale:
To calculate the profit, first determine the total revenue: 7 stands * 11 paintings per stand * $5.50 per painting = $423.50.
Then, subtract the total stand expenses ($35 per stand * 7 stands = $245) from the total revenue to get the profit: $423.50 - $245 = $178.50.
Therefore, the correct answer is $178.50. Option A is incorrect because it does not account for the stand expenses. Option C is incorrect as it does not consider the total revenue. Option D is incorrect as it overestimates the profit by not deducting the stand expenses.
Question 3 of 5
What is the perimeter of a square with a side length of 5 meters?
Correct Answer: B
Rationale: The formula to calculate the perimeter of a square is P = 4s, where P is the perimeter and s is the length of a side. Given that the side length is 5 meters, the perimeter is 4 * 5 = 20 meters.
Therefore, the correct answer is B.
Choices A (15 meters), C (25 meters), and D (30 meters) are incorrect as they do not correctly apply the formula to calculate the perimeter of a square.
Question 4 of 5
If a train travels at 80 kilometers per hour, how many kilometers will it travel in 3 hours?
Correct Answer: A
Rationale:
To find the total distance traveled, you need to multiply the speed of the train by the time it travels. So, 80 km/h * 3 hours = 240 kilometers.
Therefore, the correct answer is 240 kilometers.
Choice B (160 kilometers) is incorrect because it is the result of multiplying the speed by 2 hours instead of 3.
Choice C (240 kilometers) is the same as the correct answer, making it redundant.
Choice D (210 kilometers) is incorrect as it is the result of multiplying the speed by 2.5 hours instead of 3.
Question 5 of 5
A school has 500 students, and 60% of them are girls. How many girls are there in the school?
Correct Answer: B
Rationale: Correct!
To find out how many girls are in the school, you need to calculate 60% of 500. 60% of 500 is 0.6 * 500 = 300.
Therefore, there are 300 girls in the school.
Choice A (250 girls) is incorrect because 60% of 500 is not 250.
Choice C (200 girls) is incorrect as it is less than 300.
Choice D (350 girls) is incorrect as it is more than 300.
