Answer:
#include <bits/stdc++.h>
using namespace std;
int main() {
double time_h,temp_c;//declaring two variables for time and temperature of type double.
cout<<"Enter the time"<<endl;
cin>>time_h;//taking input of the time...
temp_c=((4*2*time_h)/(time_h+2)-20);//calculating the temperature...
cout<<temp_c<<endl;//printing the temperature..
return 0;
}
Explanation:
I have taken 2 variables of type double.
I am taking input of time from the user.
Then after that calculating the time according to the equation.
Then printing the output.
