Find the average rate of change over the interval of 2 minutes to 11 minutes
A.The rate of change is 19 of a kilometer per minute.
B.The rate of change is 9 kilometers per minute.
C.The rate of change is 13 of a kilometer per minute.
D.The rate of change is 3 kilometers per minute. **
can someone tell me if my answser is correct ?
To find the average rate of change over the interval of 2 minutes to 11 minutes, we need to divide the change in distance by the change in time.
Let's assume that the distance traveled is in kilometers.
The change in time is 11 minutes - 2 minutes = 9 minutes.
Therefore, we need to find the change in distance for the 9 minutes.
Since we only have the average rate of change options given, we can calculate the change in distance by multiplying the average rate of change with the change in time.
Option D states that the rate of change is 3 kilometers per minute.
So, the change in distance = 3 kilometers/minute * 9 minutes = 27 kilometers.
Hence, the correct option is D. The rate of change is 3 kilometers per minute.
To find the average rate of change, you need to calculate the difference in the distance traveled over the interval of time given and then divide it by the difference in the time.
Given that the interval of time is from 2 minutes to 11 minutes, the time difference is:
11 minutes - 2 minutes = 9 minutes
Now, let's say the total distance traveled over this time interval is x kilometers. The average rate of change would be:
Rate of change = (Change in distance) / (Change in time) = x kilometers / 9 minutes
However, we are not given any specific values for the distance traveled, so we cannot calculate the exact rate of change.
Therefore, the correct answer is E. The rate of change cannot be determined with the information given.
hard to say, not knowing how many km were traveled.
If D is the answer, then that must have been 27km, since
27km/9min = 3 km/min
