Until 1883,every city and town in the united states kept its own local time.today, travelers reset their watches only when the time change equals 1.0 h.how far,on the average,must you travel in degrees of longitude between the time-zone boundaries at which your watch must be reset by 1.0 h?

In 1 hour it will cover a distance of 15°

Explanation:

We know that for each rotation earth takes 24 hour

In 24 hour its travels 360° of rotation

We have to find how much we travel in 1 hour in degree

We know that 1 rotation = 360° which is completed in 24 hours

So distance traveled in 1 hour in degree will be =

So in 1 hour it will cover a distance of 15°

can you give more detail in the question? ill answer it in the comments once you post the story
