Final answer:
International travel and commerce have become faster and cheaper mainly due to technological innovations in transportation and telecommunications, which facilitate lower-cost long-distance economic activities and the digital transport of information-based products and services.
Step-by-step explanation:
International travel, communications, and commerce have been made faster and less costly primarily due to technological innovations, particularly in transportation and communication.
Improvements in shipping and air cargo have driven down transportation costs, while advances in computing and telecommunications have facilitated and reduced the costs of managing long-distance economic connections of production and sales.
Additionally, many valuable modern products and services can now be transported over telephones and computer networks at lower costs. This, combined with reductions in tariffs and quotas due to international agreements, has served to increase global trade and awareness of global markets.
Advancements in shipping and air cargo have reduced transportation costs, while improvements in computing and telecommunications have made it easier and cheaper to manage long-distance economic connections.
Information-based products and services, such as computer software and travel planning, can now be transported over telephones and computer networks at lower costs.
Overall, these innovations have facilitated greater interconnectivity and trade between countries.
