The Increase in Speed for Cowboys' Transportation

In the mid-19th century, cowboys used horses to round up and drive their herds. The speed of a cowboy's horse was said to reach up to 50 km/h. However, in the early 20th century, cowboys transitioned from horses to pickup trucks, which doubled their speed of transportation. Nowadays, cowboys have further upgraded their mode of transportation to helicopters, which have increased their speed by an additional three times.

To calculate the final speed increase, we can start with the initial speed of 50 km/h and apply the subsequent increases.

1. The transition from horses to pickup trucks doubled the speed: 50 km/h * 2 = 100 km/h. 2. The transition from pickup trucks to helicopters increased the speed by three times: 100 km/h * 3 = 300 km/h.

Therefore, the speed of cowboys' transportation has increased to 300 km/h with the use of helicopters.
