Notice that heat involves the mass of the material.

A cup of boiling water would barely effect the temperature of a bathtub full of water.

To find the actual answer, you need to know how much water is in the bathtub.
Then you set the heat loss of one = to heat gained by the other. The specific heat of water is 1 in both cases.

If the cup contained 250ml, that is 250g of water (density of water is 1g.ml)
Suppose that the tub contained 25liters or 25000g of water
Let Z = new temp
25000 X (Z- 10)= 250g X (100-Z)

Answer comes out about 10.9oC
