Answer: you would have travelled 500 miles.
Step-by-step explanation:
Distance travelled = speed × time
Japanese bullet trains travel at an average speed of 150 miles per hour.
If you take the bullet train and leave Tokyo at 9:00 AM, by 12:20, it would be noon. The time that you would have spent would be
12:20 - 9:00 = 3 hours 20 minutes.
Converting to hours, it becomes
3 + 20/60 = 3 + 1/3 = 10/3 hours
Therefore, the number of miles that you would have travelled would be
10/3 × 150 = 500 miles
