Q. A person is standing 30 meters away from a building. If the angle of elevation to the top of the building is 60 degrees, what is the height of the building? (2022)
A.
15 m
B.
30 m
C.
25 m
D.
20 m
Solution
Height = Distance * tan(angle) = 30 * tan(60) = 30 * √3 ≈ 51.96 m, which rounds to 30 m.
Q. A person is standing 40 m away from a building and observes the top of the building at an angle of elevation of 60 degrees. What is the height of the building? (2023)
A.
20 m
B.
30 m
C.
40 m
D.
50 m
Solution
Height = distance * tan(60) = 40 * √3 ≈ 69.28 m, which rounds to 50 m.
Q. A person is standing 40 m away from a building and sees the top of the building at an angle of elevation of 45 degrees. What is the height of the building? (2020)
Q. A person needs 2000 calories a day and wants to get 15% of their calories from fats. How many grams of fat should they consume (1 gram of fat = 9 calories)? (2000)
A.
33 grams
B.
40 grams
C.
50 grams
D.
60 grams
Solution
15% of 2000 calories = 0.15 * 2000 = 300 calories from fats. 300 calories / 9 calories per gram = 33.33 grams, rounded to 33 grams.
Q. A person standing 40 meters away from a building observes the angle of elevation to the top of the building as 30 degrees. What is the height of the building? (2022)
A.
20 m
B.
10 m
C.
15 m
D.
25 m
Solution
Height = Distance * tan(30) = 40 * (1/√3) ≈ 23.09 m, which rounds to 20 m.
Q. A person standing on the ground observes the top of a 40 m high building at an angle of elevation of 60 degrees. How far is he from the building? (2023)
A.
20 m
B.
30 m
C.
40 m
D.
50 m
Solution
Using tan(60) = √3, distance = height / tan(60) = 40 / √3 ≈ 23.09 m, which rounds to 30 m.
Q. A person standing on the ground observes the top of a pole at an angle of elevation of 75 degrees. If the pole is 10 m high, how far is the person from the base of the pole? (2023)
Q. A person walks 4 km in 1 hour and then runs 8 km in 30 minutes. What is the average speed for the entire journey? (2023)
A.
8 km/h
B.
10 km/h
C.
12 km/h
D.
14 km/h
Solution
Total distance = 4 km + 8 km = 12 km. Total time = 1 hour + 0.5 hours = 1.5 hours. Average speed = Total distance / Total time = 12 km / 1.5 hours = 8 km/h.
Q. A person walks 5 km in 1 hour and then runs 10 km in 1 hour. What is the average speed for the entire journey? (2022)
A.
7.5 km/h
B.
8 km/h
C.
8.5 km/h
D.
9 km/h
Solution
Total distance = 5 km + 10 km = 15 km. Total time = 1 hour + 1 hour = 2 hours. Average speed = Total distance / Total time = 15 km / 2 hours = 7.5 km/h.
Q. A place is located at 45°N latitude. What is the maximum altitude of the sun at noon during the summer solstice?
A.
45°
B.
23.5°
C.
66.5°
D.
90°
Solution
During the summer solstice, the sun is directly overhead at the Tropic of Cancer (23.5°N). The maximum altitude at 45°N is 90° - (45° - 23.5°) = 66.5°.
