Answer:
The first option will take a total of 3.2 hours while the second option will take just 3 hours 
This shows that the second option is faster 
Step-by-step explanation:
Here, we want to compare two hiking options and see the one which is faster.
At any point in time;
Distance = speed * time 
In the first option, he could hike at 3 mph for two hours.
Total distance covered would be 3 * 2 = 6 miles 
Distance left = 12 miles - 6 miles = 6 miles 
Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours 
Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours 
For the second option;
Time = distance/speed = 12 miles/4 mph = 3 hours 
We can see that the second option is faster
