A tap supplies water at 30°C while another supplies at 86°C. If a man wishes to bath with water at 44°C, calculate the ratio of mass of hot water to that of cold water required
-
1:3
- 3:1
- 3:7
- 7:3
- 15:8
The correct answer is: A
Explanation
\(M_Hc\theta_{H} = M_cc\theta_c\)\(M_h(86-44) = M_c(44-30)\) thus giving 1:3
