Tim and Jerry are business partners. Tim lives in New York (Eastern Time Zone) and Jerry lives in San Francisco (Pacific Time Zone). They both agree to meet in Oklahoma (Central Time Zone). [image of table] Tim set off at 10 am local time but shortly afterwards he realised he had left his ticket at home. As a result he missed his 4 hour flight to Oklahoma, so had to get the 12 pm (midday) flight instead. Jerry travelled by train for 2 hours to Salt Lake City (Mountain Time Zone), leaving San Francisco at 6 am local time. He then immediately boarded a bus from Salt Lake City to Oklahoma, where he arrived 6 hours later.
