Write a line of code to convert time to hours. remember there are 60 minutes in an hour. then write a line of code to calculate the speed of each runner in miles per hour. speed is distance divided by time.

float time_hourly=(time_min/60);

float speed_mph=(distance_mil/time_hourly);

Explanation:

I have taken a float variable time_hourly to convert the time given in minutes in hours.We need to divide the time in minutes by sixty since there are 60 minutes in an hour.

I have taken a float variable speed_mph to calculate the speed.Since we know the speed is distance/time and provided the distance is in miles and the time is in hours.

int giventime;

float timetohours, distance, speed;

timetohours = giventime/60;

speed = distance/timetohours;

Explanation:

The steps to achieving the above solution are as follows:

1. Determine a name for the variables that will hold the values of each entity

2. Determine the data type of the variables in step 1

3. Declare the variables and their respective datatypes

4. perform the mathematical operations as requested

Before I explain in further the steps 1-4, let me define some key words.

1. VARIABLE: a variable in programming is where data/information can be stored. Usually variables are given distinct and unique names that depict what they store in a  wat. From the solution above, we have 4 variables:

2.  DATATYPE: A Since a variable can hold data,  we have to also determine what type of data such a variable is holding. Is the data a whole number? decimal? date format? string of characters? e.t.c. This determination of what kind of data is being held within a variable is called datatype. There are several classifications of Data(datatypes) but in this example we used 2 types. Let us define them:

Now lets go ahead to explain the steps we took in achieving the solution:

1. We determined the variable names to be used. From the question we know that we will need the following details:  

time that will be converted,

the result of the conversion,

the distance and also

the resulting speed. We created 4 variables for each of these parameter.

2 Determining the variable datatype is another task. first we know that time is given in whole numbers(if not converted to hours yet, example: 20minutes, 33minutes, 46minutes and so on), so giventime will be an integer(int), however the converted time might not be a whole number, example 33 minutes will be 0.55hours. This number has a decimal place and thus we define the converted time(timetohours) as a float datatype. After that we have speed variable, we are not sure of what the resulting speed will be, however, since one of the parameters(time) that will be used to calculate the speed is already a Float datatype, there is a high tendency that the resulting value of speed will also be a float. In the light of this, we declare variable speed as float datatype. Next is the Distance, We do not know what value we will be given for the distance, so we make it open. Just in case we are not given an integer, thus distance datatype is set to float as well.

3. For the code to work, and the computer to understand our variables, we have to declare each of the variables that we have created. Declaring the variable simply means writing the variable's data type just before writing the variable. Example int giventime, float speed. In the first case, int is the datatype and the variable of datatype int is "giventime" , and in the second instance, float is the datatype andthe variable with this datatype is "speed"

4. Performing the mathematical operation:
