Answer:
The Pony Express helped mails to deliver faster from one place to another in a short period.
Explanation: Sending mails from one place to another was difficult, which took more than a week to send it to its destination. Letters sent through ships which regularly operated because of the supply of the goods. Homing pigeons, stagecoach, and railroads were some other methods to sent mails. To reduce the time a speedy mail service was introduced, which came to be known as the Pony Express. The Pony express sent letters from one place to another in a short time through a system of many riders that would gallop (ride horses) across the land to deliver mail. The fast mails help people living far from cities to be connected with recent activity and supported the military to maintain law and order in their stations.
