To find out how far the Acela Express would travel in 8 hours, we first need to calculate its speed.
The speed of the train can be calculated using the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
From the information given:
- Distance = 775 miles
- Time = 5 hours
Calculating the speed:
\[ \text{Speed} = \frac{775 \text{ miles}}{5 \text{ hours}} = 155 \text{ miles per hour} \]
Now we can find the distance traveled in 8 hours by multiplying the speed by the time:
\[ \text{Distance in 8 hours} = \text{Speed} \times \text{Time} = 155 \text{ miles per hour} \times 8 \text{ hours} = 1240 \text{ miles} \]
Thus, the Acela Express would travel 1,240 miles in 8 hours.
The correct answer is 1,240 miles.
