Every week, Tina runs 3 miles and records how long it takes to complete the run. She also records the change in time from the previous. Last week, her time running decreased by 2 minutes. What integer could represent this change.
decrease means subtract, right?
so, -2
last week her time spent running decreased by 2 minutes????. Help me pls
I would say it's -2
To find the integer that represents the change in Tina's running time, you need to determine the difference between her current week time and the previous week time. In this case, her time running decreased by 2 minutes, which means her current week time was 2 minutes less than her previous week time. Therefore, the integer that represents this change is -2.
Explanation:
1. Tina's previous week time = x minutes
2. Tina's current week time = x - 2 minutes
3. Change in time = Current week time - Previous week time = (x - 2) - x = -2 minutes
