Sample questions

1. A submarine is at 500 meters below sea level. It ascends 250 meters and then descends 150 meters. What is its final depth below sea level?

   1. -600 meters
   2. -400 meters
   3. -500 meters
   4. -300 meters
   Show answer

   Answer: B. -400 meters

   Starting depth is -500m. Ascending 250m means adding 250: -500 + 250 = -250m. Descending 150m means subtracting 150: -250 - 150 = -400m. So, the final depth is 400 meters below sea level.

2. An airplane is flying at an altitude of 12,000 meters. It descends 3,000 meters and then ascends 1,500 meters. What is its new altitude?

   1. 10,500 meters
   2. 13,500 meters
   3. 11,500 meters
   4. 9,000 meters
   Show answer

   Answer: A. 10,500 meters

   Initial altitude = 12,000 meters. After descending 3,000 meters: 12,000 - 3,000 = 9,000 meters. After ascending 1,500 meters: 9,000 + 1,500 = 10,500 meters. The new altitude is 10,500 meters.

3. The temperature on Mount Everest at noon was -15°C. By evening, it dropped by 10°C. What was the temperature in the evening?

   1. -25°C
   2. -5°C
   3. 5°C
   4. -35°C
   Show answer

   Answer: A. -25°C

   The temperature at noon was -15°C. A drop of 10°C means we subtract 10: -15 - 10 = -25°C. The temperature in the evening was -25°C.

4. A farmer plants 40 saplings. 15 saplings die, and then the farmer plants another 25 saplings. How many saplings are there now?

   1. 50
   2. 60
   3. 40
   4. 30
   Show answer

   Answer: A. 50

   The farmer starts with 40 saplings. 15 saplings die, so the number becomes 40 - 15 = 25. Then, the farmer plants another 25 saplings, so the total becomes 25 + 25 = 50 saplings.

5. A runner completes a lap in 75 seconds. How many laps can they complete in 5 minutes?

   1. 4 laps
   2. 5 laps
   3. 6 laps
   4. 7 laps
   Show answer

   Answer: A. 4 laps

   First, convert 5 minutes to seconds: 5 minutes * 60 seconds/minute = 300 seconds. Each lap takes 75 seconds. To find the number of laps, divide the total time by the time per lap: 300 seconds / 75 seconds/lap = 4 laps. The runner can complete 4 laps in 5 minutes.
