A train travels 150 miles in 3 hours. At this same rate, how many miles will it travel in 8 hours?

400

Step-by-step explanation:

speed = distance/time

speed = (150 miles) / (3 hours)

speed = 50 miles per hour

speed = distance/time

speed * time = distance

distance = speed * time

distance = 50 miles/hour * 8 hours

distance = 400 miles

Answer: 400
