Let's start the problem by determining how far Triana has left to travel after the first day. She has a total distance of 120 miles and she has already traveled 24 miles. Therefore, the remaining distance can be calculated as:
\[ 120 - 24 = 96 \text{ miles} \]
Triana wants to divide this remaining distance equally over the next three days. Let \( x \) represent the distance she will travel each day over the next three days. Since she will travel the same amount \( x \) for three days, we can express this as:
\[ 3x = 96 \]
Now, we can rewrite this equation in the form of \( px + q = r \):
\[ 3x + 0 = 96 \]
Next, we can solve for \( x \) by dividing both sides by 3:
\[ x = \frac{96}{3} = 32 \]
So, Triana will travel 32 miles each day for the remaining three days.
In conclusion, Triana will travel 32 miles each day for the next three days of her bike ride.
