The answer you are looking for is approximately 13.3 m/s.
First, writing out the formula for the speed of an object, encompassing distance and time, in meters per second, or m/s,
S=D/T.
"S" stands for "Speed."
"D" stands for "Distance."
"T" stands for "Time."
Speed (S)=????
Distance (D)=200m.
Time (T)=15s.
Substituting the given values of the variables,
S=200m/15s.
200÷15=13.3333≈13.3.
So, therefore, the final answer is approximately 13.3 m/s.
*Other answers may be a little different, depending on how you round it.
I hope that this has helped answer your question. Good day to you.
