Question

the table shows michaels average time in the 1 - mile run over 5 weeks of training. if the pattern shown in the table continues, what is michaels average time (in minutes) during the fifth week of training?
michaels training records (1 - mile run)

weekaverage time (minutes)
25:25
35:18
45:11
5?

o 5:04
o 5:07
o 5:39
o 5:01

Explanation:

Step1: Find time - difference between weeks

From week 1 to 2: $5:32 - 5:25=7$ seconds decrease.
From week 2 to 3: $5:25 - 5:18 = 7$ seconds decrease.
From week 3 to 4: $5:18 - 5:11 = 7$ seconds decrease.

Step2: Predict week 5 time

Since the time decreases by 7 seconds each week, for week 5, from week 4's $5:11$, we subtract 7 seconds. So the time is $5:04$.

Answer:

A. 5:04
