<s>[INST] Please write an algebraic circuit in Circom that takes one input and outputs 2*input. [/INST] Here is a simple circuit in Circom that takes one input x and outputs 2 * x:
template TwoTimesInput(x) => result;
    const two = 2;
    result <= two * x;
endtemplate</s>\ <s>[INST] thanks know what is the formula to calculate speed in phisichs [/INST] The main formula is Speed = Distance/ Time

where speed is inversely proportional to time. As time increases, the speed of the body will decrease and vice versa.

To find average speed, then the formula would be:

Average speed = Total distance covered / Total time taken.</s>
