Final answer:
To find the average number of miles Bilquis would have to ride each day to meet her goal, subtract the distance she has already ridden from her goal and divide it by the number of days left in the week.
Step-by-step explanation:
To find the average number of miles Bilquis would have to ride each day to meet her goal, we need to subtract the distance she has already ridden from her goal and then divide it by the number of days left in the week.
Goal distance - Distance already ridden = Remaining distance: 47.6 miles - 8 miles = 39.6 miles
Remaining distance / Number of days left = Average number of miles per day: 39.6 miles / 6 days = 6.6 miles per day
Therefore, Bilquis would need to ride an average of 6.6 miles per day to meet her goal.
