Without calculating the answer, from the choices given, which is most reasonable?. A.. 20 hours. B.. 8 hours. C.. 3.75 hours. D.. 8 minutes.

Respuesta :

Let x be the number of hours Bob needs to travel on the second day. The equation of Bob's journey is as follows,
 
                                      592 = 187 + 52x

Solving for x from this equation gives x = 7.788 hours. 

Thus, Bob needs to travel for almost 8 hours on the second day. The answer is letter B. 8 hours.
