The Correct Answer and Explanation is:
Here’s the completed table with the correct values for speed, distance, and time:
| Speed | Distance | Time |
|---|---|---|
| 40 mph | 320 miles | 8 hrs |
| 20 km/h | 60 km | 3 hrs |
| 60 mph | 120 miles | 2 hrs |
| 4 mph | 8 m | 2 hrs |
| 70 mph | 385 miles | 5.5 hrs |
| 60 mph | 45 miles | 45 minutes |
| 46 mph | 253 miles | 5.5 hrs |
| 50 km/h | 175 km | 3 hrs 30 mins |
| 50 kph | 37.5 km | 45 minutes |
| 40 km/h | 10 km | 15 minutes |
Explanation:
To determine the missing values in the table, we use the fundamental formula for motion:
Speed = Distance ÷ Time
This equation can be rearranged to solve for other variables:
Distance = Speed × Time Time = Distance ÷ Speed
We solve each row by substituting the known values into these formulas.
For example, in row 1, the given distance is 320 miles and the time is 8 hours. Using the formula Speed = Distance ÷ Time, we calculate 320 miles ÷ 8 hours = 40 mph.
In row 2, the given speed is 20 km/h and the time is 3 hours. Using the formula Distance = Speed × Time, we find 20 km/h × 3 hrs = 60 km.
In row 3, the given speed is 60 mph and the distance is 120 miles. Using Time = Distance ÷ Speed, we calculate 120 miles ÷ 60 mph = 2 hrs.
For row 4, where the given distance is 8 meters and time is 2 hours, Speed = Distance ÷ Time gives 8 m ÷ 2 hrs = 4 mph.
Each row follows the same approach, ensuring accuracy based on the equation that relates speed, distance, and time. This method is useful in real-life applications such as travel planning and logistics optimization.
