1. Problem: A car travels at a speed of 60 km/h for 2 hours. How far does it travel? 2. Formula: Distance = Speed \times Time 3. Calculation: Distance = 60 \times 2 = 120 km 4. Explanation: The distance traveled is found by multiplying the speed by the time traveled. 5. Problem: The temperature was 25°C in the morning and it dropped by 7°C in the evening. What is the evening temperature? 6. Formula: Final Temperature = Initial Temperature - Temperature Drop 7. Calculation: 25 - 7 = 18°C 8. Explanation: Subtract the temperature drop from the initial temperature to find the final temperature. 9. Problem: Find the area of a rectangle with length 8 m and width 5 m. 10. Formula: Area = Length \times Width 11. Calculation: 8 \times 5 = 40 m^2 12. Explanation: Multiply length by width to get the area of a rectangle. 13. Problem: A box has a length of 4 m, width of 3 m, and height of 2 m. Find its volume. 14. Formula: Volume = Length \times Width \times Height 15. Calculation: 4 \times 3 \times 2 = 24 m^3 16. Explanation: Multiply length, width, and height to find the volume of a box.
