Answer:

Jim needs to bike 64 miles on the last day to maintain an average of 59 miles per day.

Explanation:

To find out how many miles Jim needs to bike on the last day to maintain an average of 59 miles per day, we can use the concept of averages.


The total distance Jim needs to bike over the 6 days to maintain an average of 59 miles per day can be calculated as follows:

Total distance = Average distance per day × Number of days

Total distance = 59 miles/day × 6 days = 354 miles


Jim has already biked a total of 59 + 52 + 66 + 45 + 68 = 290 miles over the first five days.


To find out how many miles Jim needs to bike on the last day, we subtract the distance he has already biked from the total distance needed:

Distance needed on the last day = Total distance - Distance already biked


Distance needed on the last day = 354 miles - 290 miles = 64 miles


Therefore, Jim needs to bike 64 miles on the last day to maintain an average of 59 miles per day over the 6-day cross-country biking challenge.
