Write this code in MATLAB.
1. As of early 2018, Usain Bolt holds the world record in the men's 100-meter dash. It is 9.58 seconds. What was his average speed in km/h? Assign the result to a variable called hundred.
2. Kenyan Eliud Kipchoge set a new world record for men of 2:01:39 on September 16, 2018. Assign his average speed in km/h to the variable marathon. The marathon distance is 42.195 kilometers.

%Converting distance in kilometers
distance1 = 100/1000;
%Converting time in hours
time1 = 9.58/3600;
%Calculating speed
hundred = distance1 / time1
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
distance2 = 42.195;
%Calculating and Converting time in hours
time2 = (121*60+39)/3600;
%Calculating speed
marathon = distance2 / time2

y=0.1/9.58;
hundred=y*3600
x=42.195/((121*60)+39);
marathon=x*3600

I guess because 100 meter is 0.1 kilometer, but this is the problem with undocumented code.
Edit: the original comment by Priya Dwivedi was "Y u took 0.1 in the above calculation?"

The link to learningtool does not go anywhere useful. I am not sure that we as outside people would be able to see a student solution anyhow.

us_dist = 0.1
us_time = (9.58/3600)
hundred = us_dist/us_time
ken_dis = 42.195
ken_time = 2.0275
marathon = ken_dis/ken_time

%Usain
time1 = (9.58/60)/60
distance1 = 100/1000
hundred = distance1/time1
%Kenyan
time2 = 2 + (1/60) + (39/3600)
distance2 = 42.195
marathon = distance2 / time2

Posting duplicate solutions is perfectly common for Cody, but here the goal should (in my view) be to have different solutions.
I absolutely don't want to kill your enjoyment. Maybe you are the next Walter Roberson. I just want every answer to actually add something. Why encourage cheating? I'm just one person, so it is not feasible for me to spend all my time deleting duplicate answers. I do delete a lot of them, but answering new questions is much more fun.
I hope you will join 'us' in answering non-homework questions. It is a lot of fun and you can learn a lot. Some people have been programming Matlab since around the time I was born and reading their solutions is quite an education.
Given this discussion I don't think this answer should be deleted anymore, but not due to the answer itself. I hope you understand my intentions.

Thank you so much for your advice
Now I understand your point and you are right
I will definitely try my best to answer non-homework questions and learn from others' answers.
