Answer:
r = d/t
r = 200,000 meters/hour
r = 200 kilometers/hour
km/hour is more suitable
Step-by-step explanation:
Given
A falcon travels 800,000 meters in 4 hours.
This means the distance covered is 800,000 meters.
1 km equals 1,000 meters.
Therefore, the distance in kilometers is 800,000 meters divided by 1,000, resulting in 800 km.
t equals 4 hours.
Part A: To find the rate, rearrange the formula for distance, d = rt.
d = rt
By dividing each side by t, we get d/t = r.
Thus, r = d/t
Part B: Calculate the falcon's speed in meters per hour.
d = 800,000 meters
t = 4 hours
r = 800,000 meters divided by 4 hours gives us 200,000 meters/hour.
Therefore, the speed equals 200,000 meters/hour.
Part C: Find the falcon's rate in kilometers per hour.
As established, the distance is 800 km as mentioned earlier.
Hence,
speed = 800 km divided by 4 hours gives us 200 km/hour.
Part D: Which unit, meters or kilometers, is more logical for this situation, and why?
The standard measurement of speed is
km/hour and m/sec.
That is, the choice of units is based on the scale of measurement we need; larger numbers are easier to interpret in kilometers.
Since we are dealing with a large distance, it is advisable to use km/hour.
