Since Miguel has driven 2/3 of the total distance in 4 hours, we can set up a proportion to find the total time it will take him to reach his destination.
Let x represent the total time it will take Miguel to reach his destination.
We can set up the proportion:
4/2/3 = x/1
Cross-multiplying, we get:
4 = 2/3 * x
Multiplying both sides by 3/2, we get:
4 * 3/2 = x
12/2 = x
6 = x
Therefore, it will take Miguel a total of 6 hours to reach his destination. Answer: 6 hours.
