Answer :
Ryan would need to jog for 4 days each week to jog a total of 12 miles if he runs 3 miles per day.
Ryan wants to prepare for a mini-marathon by jogging 12 miles each week and if he runs only 3 miles each day, to determine the number of days he would need to jog, we divide the total weekly mileage by the daily mileage. So, we calculate 12 miles per week divided by 3 miles per day:
12 miles ÷ 3 miles/day = 4 days.
Therefore, Ryan would need to jog for 4 days each week to reach his goal of jogging 12 miles per week.
