Understanding Distance, Speed, and Time
When calculating the distance a bird flies, we can use the basic formula of distance, which relates speed, time, and distance.
Given Information:
- The bird's speed is 2 kilometers per minute.
- We want to express the distance in terms of time (t).
Distance Formula:
The relationship can be expressed as:
Distance = Speed × Time
In this case, the speed of the bird is constant at 2 kilometers per minute.
Expressing Distance in Terms of Time:
- If we let 't' represent the time in minutes, we can substitute this into the formula.
- Therefore, the distance the bird travels can be expressed as:
Distance = 2 kilometers/minute × t minutes
Final Expression:
- This simplifies to:
Distance = 2 * t kilometers
Hence, the correct option to express the distance flown by the bird in terms of time is option 'A' (2 * t).
Why Other Options Are Incorrect:
- Option b (t / 2): This suggests the distance decreases as time increases, which is incorrect.
- Option c (2 / t): This implies the distance is inversely related to time, which does not apply here.
- Option d (t + 2): This does not reflect any relationship between speed and time.
Conclusion:
Understanding how to relate speed and time is crucial in solving such problems, and option 'A' accurately captures the relationship for the bird's flight distance.
