To find out how far the Acela Express traveled in 8 hours, we can use a proportion based on the given information.
If the Acela Express traveled 775 miles in 5 hours, we can set up the following proportion:
5 hours / 775 miles = 8 hours / x miles
To solve for x, we can cross-multiply and then divide:
5 * x = 8 * 775
5x = 6200
x = 6200 / 5
x = 1240 miles
Therefore, the Acela Express traveled 1240 miles in 8 hours.
To determine how far the Acela Express, the fastest train in North America, traveled in 8 hours, we can use the concept of average speed.
We are given that in 5 hours, it traveled 775 miles. To find the average speed, we divide the total distance by the time taken.
Average speed = Total distance / Time taken
Using the given information:
Average speed = 775 miles / 5 hours = 155 miles/hour
Now that we have the average speed, we can calculate the distance traveled in 8 hours by multiplying the average speed by the time:
Distance traveled in 8 hours = Average speed * Time taken
Distance traveled in 8 hours = 155 miles/hour * 8 hours
Distance traveled in 8 hours = 1,240 miles
Therefore, the Acela Express would travel 1,240 miles in 8 hours.
