Answer:
Takes maria
Explanation
Maria's rate of speed is 46.5 kilometers per hour.
What is the distance?
Distance is defined as the product of speed and time.
Since there are 3600 seconds in an hour, we can divide the time it takes Gretchen to travel 4400 meters by 3600 to find the number of hours it takes her:
⇒ 340 seconds / 3600 seconds/hour = 0.09444444 hours.
Next, we need to convert the distance she travels to kilometers. Since there are 1000 meters in a kilometer, we can divide the distance Maria travels by 1000 to find the number of kilometers she travels:
⇒ 4400 meters / 1000 meters/kilometer = 4.4 kilometers.
Now that we have the distance Maria travels and the time it takes her to travel that distance in the appropriate units, we can divide the distance by the time to find her rate of speed in kilometers per hour:
⇒ 4.4 kilometers / 0.09444 hours = 46.5882375 kilometers/hour.
Thus, Maria's rate of speed is 46.6 kilometers per hour.
