The study of chemicals and bonds is called chemistry. There are different types of elements and these are metals and nonmetals.
The correct answer is 5 hours.
The rate at which the distance is covered is called speed.
According to the question, the formula used to solve the question is as follows:-
[tex]D =S*T[/tex]
[tex]65*2=130[/tex]
The total distance covered is 364. The remaining distance will be:-
[tex]364-130 = 234[/tex]
The average speed is 78kh/h.
Hence, the time required to complete the distance is:-
324/78 = 3
Therefore the total time taken is 2+3 =5
