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.
Max's biking time at the beginning was 90 minutes. Max's biking time at the end was 81 minutes.
So, Max improved his biking time by 9 minutes.
Step-by-step explanation: ___..
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.
