Exercise 14 Page 91

Can you identify a pattern of change between each row in the table?

4/3

Practice makes perfect

To determine the rate of change in distance for the car in the task, let's see if we can identify a pattern of change between each row in the given table.

Change in Time Time Distance Change in Distance
15 20
+15 ↪ 30 40 +20 ↩
+15 ↪ 45 60 +20 ↩
+15 ↪ 60 80 +20 ↩
+15 ↪ 75 100 +20 ↩
Rate of change is defined as the change in dependent variable over the change in independent variable. rate of change=Change in distance/Change in time Looking at the patterns of change in the table, we see that every time the value of time increases by 15, distance increases by 20. We can substitute these values into the equation to obtain the rate of change.

rate of change=Change indistance/Change intime
rate of change=20/15
rate of change=4/3
