A 2-day automobile trip of 880 miles is planned. Half of this distance is to be traveled each day at a rate of 55 miles per hour. How many hours will be driven each day, given that D=RT? (D = Distance, R = Rate, T = Time)

Solution:
1. Determine the total distance to be traveled each day:
* Total distance: 880 \text{ miles}
* Half the distance per day: \frac{880}{2} = 440 \text{ miles}

2. Use the formula for distance, rate, and time:
* Formula: D = R \cdot T
* Given:
- Rate, R = 55 \text{ miles per hour}
- Distance per day, D = 440 \text{ miles}

3. Solve for time, T:
* Substitute into the formula:
440 = 55 \cdot T
* Solve for T:
T = \frac{440}{55} = 8 \text{ hours}

Each day, they will drive for a total of 8 \text{ hours}.
