Question

in c please

Write a program that estimates the temperature in a freezer (in C) given the elapsed time (hours) since a power failure. Assume this temperature (T) is given by 20 t+2 where t is the time since the power failure. Your program should prompt the user to enter how long it has been since the start of the power failure in whole hours and minutes. Note that you will need to convert the elapsed time into hours. For example, if the user entered 2 30 (2 hours 30 minutes), you would need to convert this to 2.5 hours

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

//code

#include<stdio.h>

//method to find the temperature T using the given formula

float findTemperature(float time){

              //applying equation

              float temp=((4*time*time)/(time+2))-20;

              return temp;

}

int main(){

              //declaring variables

              int hours, minutes;

              float totalHours=0;

              //prompting user for hours and minutes

              printf("How long it has been since the start of power failure?\n");

              printf("Hours: ");

              scanf("%d",&hours);

              printf("Minutes: ");

              scanf("%d",&minutes);

              //assuming inputs are valid

              totalHours+=hours; //adding hours to total time

              totalHours+=(float) minutes/60.0; //adding minutes/60 to total time

              //finding temperature

              float temp=findTemperature(totalHours);

              //displaying temperature with a precision of 2 digits

              printf("Estimated temperature: %.2f degree celsius\n",temp);

              return 0;

}

/*OUTPUT*/

How long it has been since the start of power failure?

Hours: 2

Minutes: 30

Estimated temperature: -14.44 degree celsius
