Final answer:
Jerel runs 4.8 kilometers on the fifth day. This is found by subtracting the total distance he runs over the first four days, which is 9.2 kilometers, from the total weekly distance of 14 kilometers.
Step-by-step explanation:
To calculate how many kilometers Jerel runs on the fifth day, we need to subtract the total distance he runs on the first four days from the total weekly distance. First, we multiply the daily distance he runs on 4 days, which is 2.3 km, by 4 to get the total distance covered in those 4 days.
2.3 km/day × 4 days = 9.2 km
Now, we know Jerel runs a total of 14 km every week. To find out the distance he runs on the fifth day, we subtract the 9.2 km he has already run from the total weekly distance.
14 km - 9.2 km = 4.8 km
Therefore, Jerel runs 4.8 kilometers on the fifth day.
