ISAT Quantitative Reasoning with Units 2 — Questions and Answers
Question 1: A car travels 240 miles in 4 hours. What is its average speed in feet per second? (1 mile = 5,280 feet)
- 88 ft/s (Correct answer)
- 60 ft/s
- 176 ft/s
- 44 ft/s
Correct answer: 88 ft/s
240 miles/4 hours = 60 mph; 60 × 5280 / 3600 = 88 ft/s.
Question 2: A recipe calls for 2.5 liters of broth. If you only have a measuring cup marked in fluid ounces (1 L ≈ 33.8 fl oz), approximately how many fluid ounces do you need?
- 84.5 fl oz (Correct answer)
- 67.6 fl oz
- 13.5 fl oz
- 101.4 fl oz
Correct answer: 84.5 fl oz
2.5 × 33.8 = 84.5 fluid ounces.
Question 3: A field has an area of 3.6 hectares. How many square meters is this? (1 hectare = 10,000 m²)
- 36,000 m² (Correct answer)
- 3,600 m²
- 360,000 m²
- 360 m²
Correct answer: 36,000 m²
3.6 × 10,000 = 36,000 m².
Question 4: A pump moves water at 45 gallons per minute. At this rate, how many hours will it take to fill a 16,200-gallon tank?
- 6 hours (Correct answer)
- 360 hours
- 0.1 hours
- 3 hours
Correct answer: 6 hours
16,200 ÷ 45 = 360 minutes = 6 hours.
Question 5: A gold bar weighs 400 troy ounces. If 1 troy ounce = 31.1 grams, what is the mass of the bar in kilograms?
- 12.44 kg (Correct answer)
- 1,244 kg
- 124.4 kg
- 1.244 kg
Correct answer: 12.44 kg
400 × 31.1 = 12,440 g = 12.44 kg.
Question 6: The pressure in a tire is 32 psi (pounds per square inch). If 1 psi ≈ 6,895 pascals, what is the pressure in kilopascals (kPa)?
- 220.6 kPa (Correct answer)
- 2,206 kPa
- 22.06 kPa
- 0.2206 kPa
Correct answer: 220.6 kPa
32 × 6,895 = 220,640 Pa = 220.6 kPa.
Question 7: A runner completes a 10 km race in 50 minutes. What is her speed in meters per second?
- 3.33 m/s (Correct answer)
- 0.2 m/s
- 200 m/s
- 12 m/s
Correct answer: 3.33 m/s
10,000 m ÷ 3,000 s = 3.33 m/s.
