We can see that the two times taken by the student to complete two different assignments are provided in cells: B2 and B3, and we wish to calculate the total time taken by a student in cell B4.
Any stopping time is a hitting time for a properly chosen process and target set. For example, the sum $\tau_1 + \tau_2$ of two stopping times is, while for stochastic processes in continuous time, the product $\tau_1 \cdot \tau_2$ need not be. So, the finer the filtration, the larger the collection of stopping times.
Determined here for each positive integer $n$ are those functions $\phi$ for which $\phi(\tau)$ is a stopping time for all $n$-triples of stopping times $\tau = \tau_1, \cdots, \tau_n$. For example, suppose Alice flips a fair coin n times. �T��+�h��/�h:B�O#�PQ���Y�º3��|+�M�B�r-���LB���;4^�֬8rr��L�#dl�Y
So, we sum the two given times in excel using SUM () function and we get the desired result- 14 hours for completion of two assignments. �v\�0�^�@�#�XGz~������c�L���{�����9Srgn&�_��&У�е����6A���p̽z�!�@��Kn�h�%dz�֞���\���v����(թ�K�B�I8e1_�A��._��I ؽP{M��3�Ka�M�ǶN�Q�5���ef�@���9>��tHy�#7��ă�����ė0ڊ�

We can use the kinetic energy idea, and a knowledge of driver reaction times, to write an equation that predicts car stopping distances ("stopping" distance is the sum of reaction and braking distance). D&D Beyond

The total stopping distance is the sum of the perception-reaction distance and the braking distance. {�� �U8��Ek�_���-%���Kj�S����d ��G�Ϥ-�fl�ûO�i�5�] �K.��~�ǻm��3m��x� |� �v��ː�� ��>!M'lu
The Start/End times columns are nvarchar and I am declaring them as datetime. For example, the sum $\tau_1 + \tau_2$ of two stopping times is, while for stochastic processes in continuous time, the product $\tau_1 \cdot \tau_2$ need not be. Probab. I'm not sure if that is my first step or not, I am new to SQL and to declaring. Some functions of stopping times are necessarily stopping times, but others need not be.

Here is the equation's canonical form: This follows from the converse of the Début theorem (Fischer, 2013).
