If she wants her average speed to be 4 miles per hour, what speed (in miles per hour) does she need to walk the remaining distance? Answer:<|im_end|> <|im_start|>assistant 6 1 [6] [stop:-] To determine the speed Marissa needs to walk the remaining distance to achieve an average speed of 4 miles per hour, we can follow these steps: 1. **Calculate the total time required to achieve the desired average speed:** The desired average speed is 4 miles per hour. The total distance of the trail is 12 miles. Therefore, the total time required to cover 12 miles at 4 miles per hour is: \[ \text{Total time} = \frac{\text{Total distance}}{\text{Average speed}} = \frac{12 \text{ miles}}{4 \text{ miles per hour}} = 3 \text{ hours} \] 2. **Determine the time already spent walking:** Marissa has already spent 1 hour walking the first 4 miles and another hour walking the next 2 miles. Therefore, the total time already spent is: \[ \text{Total time already spent} = 1 \text{ hour} + 1 \text{ hour} = 2 \text{ hours} \] 3. **Calculate the remaining time needed to walk the remaining distance:** The remaining distance to be walked is 12 miles - 4 miles - 2 miles = 6 miles. The remaining time needed is: \[ \text{Remaining time} = 3 \text{ hours} - 2 \text{ hours} = 1 \text{ hour} \] 4. **Determine the required speed for the remaining distance:** To find the required speed, we use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \] Substituting the remaining distance and remaining time: \[ \text{Required speed} = \frac{6 \text{ miles}}{1 \text{ hour}} = 6 \text{ miles per hour} \] Therefore, Marissa needs to walk the remaining distance at a speed of \(\boxed{6}\) miles per hour.
