Question

joan records how many minutes she walks each day.
what was the average number of minutes joan walked per day?
54
59
60
63

Explanation:

Step1: Calculate total minutes walked

$$60 + 54+59 + 63+66+54+57$$
$$=(60 + 54)+(59 + 63)+(66 + 54)+57$$
$$=114+122+120+57$$
$$=(114 + 122)+(120 + 57)$$
$$=236+177$$
$$=413$$

Step2: Calculate average

Number of days \(n = 7\).
Average \(=\frac{413}{7}=59\)

Answer:

59
