To Meme Sir: aw, great *sighs in annoyance*

Kiki, calm down. He needs help.

0.55 is close to 0.5, and 1.4 is close is 1.5. Keri walks
approximately 0.5 × 5 + 0.75 × 2 = 2.5 + 1.5 = 4 km per week.

To calculate how many kilometers Keri walked in one week, we need to determine the lengths of the walks on weekdays and weekends, and then add them up.

Step 1: Calculate the length of the walk on weekdays (Monday to Friday)
The length of the walk on each weekday is given as 0.55 kilometers.

Step 2: Calculate the length of the walk on weekends (Saturday and Sunday)
The length of the walk on weekends is 1.4 times as long as a walk on a weekday. So we need to multiply the length of a weekday walk (0.55 km) by 1.4.
Length of weekend walk = 0.55 km * 1.4 = 0.77 km

Step 3: Calculate the total length of the walks in one week
To calculate the total length of the walks in one week, we need to add the lengths of the weekday walks and the weekend walks.
Total length = (Length of weekday walk * number of weekdays) + (Length of weekend walk * number of weekends)

Assuming there are 5 weekdays and 2 weekends in a week:
Total length = (0.55 km * 5) + (0.77 km * 2)
Total length = 2.75 km + 1.54 km
Total length = 4.29 km

Therefore, Keri walked 4.29 kilometers in one week.
