HESI A2 Math Questions
Question 1 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 2 of 5
A marathon runner completes 21.6 miles and burns 2,274 calories. What is the rate of calories burned per mile?
Correct Answer: A
Rationale: To find the rate of calories burned per mile, divide the total calories burned by the total distance covered. In this case, 2,274 calories ÷ 21.6 miles = 105.28 calories per mile (rounded to two decimal places), which matches option A. This calculation is based on the fundamental concept of division, where the total calories are distributed evenly over the total distance. Choices B, C, and D are incorrect as they do not match the calculated rate. This question tests basic division skills and understanding of calculating rates.
Question 3 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 4 of 5
4 7/8 divided by 1 1/6 equals what?
Correct Answer: D
Rationale: To divide mixed numbers, convert them to improper fractions, then multiply by the reciprocal of the divisor. 4 7/8 = 39/8 1 1/6 = 7/6 (39/8) ÷ (7/6) = (39/8) * (6/7) = 234/56 = 4 5/28 Therefore, the correct answer is D: 4 & 5/28. Choice A is incorrect as it doesn't represent the correct division result. Choices B and C are also incorrect because they do not match the calculated result of 4 5/28.
Question 5 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.
