Answer:
480 miles
Equation:
[tex]t=60w, w=number \ of \ week, t=time \ in \ minutes.[/tex]
Step-by-step explanation:
#First we calculate the average time it takes to walk one mile:
[tex]\bar x=\frac{1}{n}\sum(x_i)}\\\\=\frac{1}{2}(14+16)\\\\=15\ min[/tex]
#We then calculate the number of miles he walks in 8 weeks.
-Given he walks one mile per day, 4 times a week;
[tex]Total \ Distance=4\times 1\times 8\\\\=32\ miles[/tex]
#Multiply the distance traveled by the average time per mile to get total time spent:
[tex]t=miles\times min/mile\\\\=15\times 32\\\\=480\ minutes[/tex]
Hence, the walking time over the 8 period will be 480 minutes
#This can be represent as:
Let w be the number of weeks and t be the time in minutes.
The time spent on walking per week is [tex]4\times 15=60\ minutes[/tex]
Therefore the time spent walking in w weeks is represented as:
[tex]t=60w, w=number \ of \ week, t=time \ in \ minutes.[/tex]
