Answer:To find out how Max's biking time changed, we can calculate the difference between his first practice time and his last practice time for biking.

Answer:

Max improved his biking time by 9 minutes.

Step-by-step explanation:

To determine the amount of change in Max's time for each event, we subtract his last practice time from his first practice time.

For the running event:

Amount of change = Last practice time - First practice time

= 68 minutes - 80 minutes

= -12 minutes

For the swimming event:

Amount of change = Last practice time - First practice time

= 48 minutes - 60 minutes

= -12 minutes

For the biking event:

Amount of change = Last practice time - First practice time

= 81 minutes - 90 minutes

= -9 minutes

So, Max improved his running time by 12 minutes, his swimming time by 12 minutes, and his biking time by 9 minutes.

Therefore, Max improved his biking time by 9 minutes.
