Question

Selena is training for a race. Last week, she ran 4 miles each day on 3 different days. Use the symbol X to make an array that represents the total number of miles Selena ran last week.

Answer 1

To represent the total number of miles Selena ran, create an array with 3 rows of 4 'X' symbols each. This visualizes that she ran 4 miles on each of 3 days, totaling 12 miles for the week.

Step-by-step explanation:

The question asks to illustrate using an array how many miles Selena ran last week, given that she ran 4 miles each day on 3 different days. To represent this scenario with the symbol X, we can visualize an array where each X represents one mile. The array to show the total number of miles Selena ran is as follows:

X X X X

X X X X

X X X X

Here, each row represents a day Selena ran, and each X in that row represents one mile. Since there are 3 rows of 4 X's each, this means Selena ran a total of 12 miles last week (3 days times 4 miles each day).

So to calculate the total miles, you simply multiply the number of days she ran by the number of miles she ran each day:

Total miles = Number of days × Miles per day

Total miles = 3 × 4 = 12 miles

Therefore, Selena ran a total of 12 miles during those three days of training.
