Josiah wants to ride his bicycle 42.5 miles this week. He has already ridden 18 miles. If he rides for 5 more days, what is the average number of miles he would have to ride each day to meet his goal?





To find the average number of miles Josiah needs to ride each day for the next 5 days to meet his goal of 42.5 miles, we can follow these steps:

1. **Calculate the Remaining Distance:**

   Josiah's total goal is 42.5 miles, and he has already ridden 18 miles. We need to calculate how many more miles he needs to ride.

   \[
   \text{Remaining distance} = \text{Total distance} - \text{Distance already ridden} = 42.5 - 18
   \]

   \[
   \text{Remaining distance} = 24.5 \text{ miles}
   \]

2. **Calculate the Average Miles per Day:**

   Josiah has 5 more days to ride these 24.5 miles. To find out how many miles he needs to ride each day on average, we divide the remaining distance by the number of days.

   \[
   \text{Average miles per day} = \frac{\text{Remaining distance}}{5} = \frac{24.5}{5}
   \]

   \[
   \text{Average miles per day} = 4.9 \text{ miles}
   \]

Therefore, Josiah needs to ride an average of 4.9 miles each day for the next 5 days to meet his goal of 42.5 miles.

If you have any questions or need further assistance, feel free to ask. Here are some additional questions for practice:

1. If Josiah decides to ride for only 4 more days instead of 5, how many miles per day would he need to ride to meet his goal?
2. What would be the total number of miles Josiah would ride if he decided to ride 5.5 miles each day for the next 5 days?
3. If Josiah increased his weekly goal to 50 miles, how many miles would he need to ride per day for the next 5 days?
4. How many additional miles would Josiah need to ride over the next 5 days if his goal increased by 10%?
5. If Josiah rides 3 miles on the first of the remaining 5 days, how many miles per day does he need to average for the next 4 days?
6. If Josiah can ride only 3 days out of the remaining 5 days, what is the average number of miles he needs to ride each day to meet his goal?
7. How many total miles will Josiah ride if he completes his goal and then decides to ride an additional 2 miles each day for the remaining 5 days?
8. If Josiah rides 5 miles on the first of the remaining 5 days, how many miles per day does he need to average for the next 4 days?

**Tip:** When dealing with average calculations, always ensure the total is divided by the correct number of items or days to get an accurate average.
