The first airplane wasn't flown in 1920, it ws flown in 1903. By 1920, dozens of different aircraft were being flown.
Aircraft can go up to about 1,600 mph .
Depends on the speed of the airplane and the landing delays.
an aeroplane can go between 500-600 mphThe average speed of an airplane is about 500-600 mph
Yes, the Wright brothers built and successfully tested the first airplane, but I think that Leonardo Da Vinci made plans for something that resembled an airplane. If it's for homework then go with the Wright brothers.
An aeroplane can fly at around 500 miles an hour.

The first locomotive was built by Richard Trevithick and had a top speed of about 4 mph (miles per hour).
If you need to go a long ways, if you need to go fast, or if you need to carry a lot of weight.
no, it slowly picks up speed throughout the travel to the end of the launch strip.
There's no such thing as an 'average' airplane. The range of speeds among aircraft from ultralights to supersonic jet fighters is perhaps from 20 to 2,000 miles per hour.
The first automobiles were built in Germany in the 1880s. There were test vehicles built a few years before that, but, they were not automobiles as we know it. The 1880s cars could only go a few miles per hour.
