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
An example of a linear equation is : y=mx+b.
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.
"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.
