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 calculate the distance traveled, multiply the speed (60 mph) by the time (2.5 hours): 60 mph * 2.5 hours = 150 miles. Therefore, the correct answer is B. Choice A (120 miles) is incorrect as it is lower than the correct calculation. Choices C (180 miles) and D (170 miles) are incorrect as they are higher than the actual distance traveled.
Question 2 of 5
Square: A garden bed has a side length of 8 meters. What is its perimeter?
Correct Answer: C
Rationale: To find the perimeter of a square, we add up all four sides. Since the garden bed has a side length of 8 meters, each side is 8m. Therefore, the perimeter = 8m + 8m + 8m + 8m = 32m (Choice C). Choices A, B, and D are incorrect because they do not correctly calculate the total length of all four sides of the square.
Question 3 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 4 of 5
Train A leaves the station at 1:45 traveling at a constant speed of 65 mph. If it arrives at its destination at 3:15, how many miles did it travel?
Correct Answer: A
Rationale: To calculate the distance traveled by Train A, we use the formula Distance = Speed x Time. The time taken by the train is 3:15 - 1:45 = 1.5 hours. Therefore, Distance = 65 mph x 1.5 hours = 97.5 miles. Choice A is correct because it correctly calculates the distance using the speed and time provided. Choices B, C, and D are incorrect as they do not calculate the distance correctly based on the given information.
Question 5 of 5
If Larry can wash 50 cars in 20 minutes, how many minutes will it take him to wash 80 cars?
Correct Answer: B
Rationale: To find the time to wash 80 cars, we use the formula: Time = (Number of cars * Time taken for 1 car)/(Number of cars washed in that time). Time = (80 * 20)/(50) = 32 minutes. Choice B is correct. Choice A is incorrect as it assumes the time taken is constant. Choice C and D are incorrect as they do not consider the increase in the number of cars to be washed.
