Given
The given parameters show that P is a point between O and Q.
So:
Substitute values for OP, PQ and OQ

Make x the subject
The answer is 1/8. When we take out the LCM and and make the denominators same we get the answer.
Simply follow the units into quantities
E/(mT) = c
Where
E = energy
m = mass
T = temperature
c = specific heat
Solving for T
358/(15*T) = 0.385
T = 62°C
