You improve your time running a course by 5 seconds in week one, by 3 seconds in week two, and by 4 seconds in week three. What is the average weekly change in your running time?
Can anyone help me with this problem pls.. Thanks
(5+3+4)/3 = 4
its 4
Yeah I need help on this problem too. I can't figure this one out.
It’s four 😀
It is 4
-5 + (-3) + (-4)
-5 + (-3) = -12
-12 divide 3 = -4
BE HAPPY DON'T STRESS!!!!!!
Of course! I can help you with this problem. To find the average weekly change in your running time, you need to calculate the total change in your running time and divide it by the number of weeks.
First, let's find the total change in your running time. According to the given information, in week one, you improved your time by 5 seconds. In week two, you improved your time by 3 seconds. And in week three, you improved your time by 4 seconds. To find the total change, you need to add up these values: 5 seconds + 3 seconds + 4 seconds = 12 seconds.
Next, let's find the number of weeks. In this case, you improved your time over a period of three weeks, so the number of weeks is 3.
Now, we can calculate the average weekly change by dividing the total change (12 seconds) by the number of weeks (3): 12 seconds / 3 weeks = 4 seconds per week.
Therefore, the average weekly change in your running time is 4 seconds.
