Could some body help me please
Thank you

The code is horrible. You still have a lot to learn.
But first:

float calculate_mile_per_hour(float miles, float minutes) //; there's no semicolon here!!!

{

float mile_per_hour;

miles_per_hour = (miles * 60)/minutes);



return (mile per hour);

}

I agree.. this is painful ..

To add to what Sci@phy told you, take a closer look at this

float calculate_mile_per_hour(float miles, float minutes);

{

float mile_per_hour;

miles_per_hour = (miles * 60)/minutes); 

return (mile per hour);

}

First of course, remove the semi-colon from all of your function definitions. Now, you declare your variable as mile_per_hour .. then on the next line you have miles_per_hour and you are trying to return mile per hour ... Your variable names ALL need to be exactly the same.. and you cannot have spaces in a variable name.

Read your code very carefully, and go through your compile errors and fix one line at a time. You need to read and understand your compile errors.
