1 answer:
Answer:
3/16 miles/minute
Step-by-step explanation:
<em>A rate of change describes how an output quantity changes relative to the change in the input quantity. </em>
<u>Points given:</u>
Input Output
2 1/6
3 17/48
4 13/24
5 35/48
6 11/12
Here input values describe the time in minutes from 2 to 6 and output values describe the distance in miles from 1/6 to 11/12
<u>Calculating the rate of change using the first two pairs of input-output values</u>
- Relative change = change in distance/change in time
- (17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles/minute
We will get the same result if we take any other ordered pair of input and output values.
