There is a whole range of speeds at which you are allowed to drive, not just one. In cases like this where there is more than one correct answer, we use inequalities, not equations, to represent the situation.
Inequalities are mathematical statements that define a range of values. They are easily recognizable because they contain the symbols <, ≤,>, or ≥.
We find the length of the arc followed by the needle. For this, we first need to convert the subtended angle to radians: 96/∅ = 180/π ∅ = 1.68 rad S = r∅ S = 24 x 1.68 Distance covered by needle = 40.32 cm
