Answer:

B.He did not add the corresponding parts of the complex numbers.

Step-by-step explanation:

A mid point is a point that is of equal distance to two reference points.

Given: Find the midpoint of 5+(-3)i and 12+7i.

These expressions have two parts: the value and complex number parts.

Thus the addition ought to have been;

(5+(-3i)) + (12+7i) = (5 - 3i) + (12 + 7i)

                           = (5 + 12) + (-3i + 7i)

                           = 17 + 4i

The midpoint can be determined as:

                       

Thus it can be observed that Raul did not add the corresponding parts of the complex numbers..

Okay. I'm sure you are familiar with the DST triangle, yes? It will help you solve this problem. Distance/speed = time. 382/64 = 5.96875. Round to the nearest hundredth to get 5.97 hours.
