There was no word problem, so it would be a null equation.
Yes. That's why it's called a linear equation
It is not. It is called a LINEAR equation. This is because the word linear refers to a line and, if the solutions of the equation, in the form of ordered pairs (x,y), were plotted on a Cartesian plane, they would all lie on a straight line.

you shall add
Use the equation, speed = distance / time, substitute in the given information from the problem and solve it.
It is an equation which, if plotted will be represented by a straight line (hence linear).
The word straight doesn't really apply to an equation. However the graph of a linear equation is a straight line.
Please solve this equation.
Without an equality sign the given expression can't be considered to be an equation
If there are two variables, you'll usually need two equations in the two variables, to be able to find a specific solution. How you write the equation depends on the specific problem. In general, it requires some practice, to be able to convert a word problem into mathematical equations.
An example of a linear equation is : y=mx+b.
"Try as he might, he could not solve the equation."
Yes. That's why it's called a linear equation
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
