Of course, speed is dependent on time. The logic behind this is very easy to understand, even if you are not a physicist. Speed refers to the rate at which something moves. So, if an object is moving very fast, the total time taken for it to get to its final destination will reduce. Also, if an object is moving very slow, it will take it a very long period of time to get to its final destination, and the total time taken will increase.
This will also reflect in your calculations. Let's say an object covers a distance of 16 meters in 4 seconds, then the calculated value for speed will be 4 m/s. Also, let's assume we are to calculate the value for time and the distance is still constant i.e., 16 meters. Also, speed =8m/s. Then, Time= Distance/speed, Time=16/8= 2s. This shows that the higher the speed, the lower the time is taken, vice versa.
