...I, uh. ...hm.

function distanceMiles = CalculateDistance(timeHours, rateKPH)
% timeHours: Time in hours
% rateKPH: Rate in kilometers

rateMPH = rateKPH; % Call KilometersToMiles function (below) to assign
% rateMPH with the corresponding speed in miles per hour

distanceMiles = rateMPH * timeHours;

end

% Do not modify the function below
function milesValue = KilometersToMiles( KilometersValue )
milesValue = KilometersValue * 0.6213712;
end

...I was doing an assignment.
