Question 3
write a program that estimates the temperature in a freezer (in Celsius)
given the elapsed time (hours) since a power failure. Assume this temperature (T) is given by

T=(4t^2/(t+2)) - 20

where t is the time since 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 will need to convert this to 2.5 hours.

Explanation / Answer

please rate - thanks

#include<iostream>
using namespace std;
int main()
{double t,T;
int h,m;
cout<<"how long it has been since the start of the power failure in whole hours and minutes: ";
cin>>t;
h=(int)t;
m=(int)(t*100);
m=m%100;
t=h+m/60.;
T=(4*(t*t)/(t+2))-20.;
cout<<"The freezer temperature is currently about "<<T<<endl;
system("pause");
return 0;
}
