There are 50 x 4 = 200 gaps of 20 metres.
So you need 1 post at the start and 200 at the end of each 20 metres, making 201 posts

What is the average speed between four and five minutes?
Calculation of speed requires distance as well as time. No information on distance given.
What is the distance between points C and F?

What is distance distance between two points?
In plane geometry, the shortest distance between two points is a line. In spherical geometry, the shortest distance between two points is a segment of a great circle. The distance between one point and another is known as the displacement.
Does perpendicular lines have a constant distance between them?
No but parallel lines have a constant distance between them
What is the distance between -3 and 0?

When you straighten your fingers out are you extending or flexing?
When you straighten your fingers out, you are extending them. Flexing refers to bending the joints to decrease the angle between bones, while extending refers to straightening the joints to increase the angle between the bones.
What is the distance between the effort and fulcrum?
The distance between the effort and the fulcrum is known as the effort arm. It determines the amount of force required to move an object when using a lever. A longer effort arm requires less force to move the object, while a shorter effort arm requires more force.
What is relationship between magnification and working distance?
As magnification increases, the working distance decreases. A higher magnification typically requires the object to be closer to the lens in order to be in focus, resulting in a shorter working distance. Conversely, a lower magnification allows for a greater working distance between the object and the lens.
How far is north Cyprus from Britain?
The distance between them is roughly 3100 kilometers and requires a four hour direct flight.
Why cesium requires little energy to release its one elecron of outermost shell?
The distance between the nucleus an this electron is higher.
What was the fastest way to send a message long distance in the 1800?
the 1800's was the time when people really started working for their benefits, and of course they had trade between each other. So, the best way to communicate between each other is through letters, that was not so developed but at least they could know what was occurring.
Had the telegraph been in existence the War of 1812 might never have occurred?
Yes, this is true; if the telegraph had been in existence at that time, then the War of 1812 would not have happened because the telegraph could have sped up communications between England and the U.S.
What is the distance from Paris France to Mexico City?
There is a pretty long distance of 9,204 Kilometers (5,719 miles) between both cities. It requires a trip of 13 hours or so by plane.
When was the underwater telegraph invented?
1850, between England and France.
How does magnification affect working distance microscope?
Increasing the magnification of a microscope typically decreases the working distance, or the distance between the objective lens and the specimen. Higher magnification requires the objective lens to be closer to the specimen to achieve focus, reducing the working distance. Similarly, lower magnification allows for a greater working distance between the lens and the specimen.
Who built the telegraph?
Samuel Morse was the father of the telegraph and of Morse code. He built his first line between Washington DC and Baltimore in 1843.
