Question

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, how many miles you have travelled at 12:20

Answer 1

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
