GIVEN: Starting from point A of the cube shown below, a beetle can travel around the bottom
perimeter in exactly four minutes. NOTE: the beetle can climb up or across the cube's sides.
REQ'D: Answer the following Questions:
1. What is the minimum amount of time it would take the beetle to get from point A to point B,
assuming it travels at the same rate of speed as it did around the perimeter?
2. How many different solutions are there?

Step-by-step explanation:

To solve this problem, we need to consider the shortest path for the beetle to travel from point A to point B while following the perimeter of the cube. Since the beetle can climb up or across the cube's sides, it can traverse the edges of the cube.

Given:

- Time taken to travel around the bottom perimeter of the cube: 4 minutes

1. To find the minimum time for the beetle to travel from point A to point B:

- The shortest path from point A to point B follows the bottom perimeter for 3 edges and then climbs up the vertical edge to reach point B.

- Since each edge takes 4 minutes to traverse, and there are 3 edges to traverse horizontally, the time taken for horizontal traversal is 3 * 4 = 12 minutes.

- Additionally, the beetle needs to climb up one vertical edge, which also takes 4 minutes.

- Therefore, the minimum amount of time for the beetle to travel from point A to point B is 12 minutes (horizontal traversal) + 4 minutes (vertical traversal) = 16 minutes.

2. To determine the number of different solutions:

- There is only one shortest path for the beetle to travel from point A to point B, as described above.

- Therefore, there is only one solution.

In summary:

1. Minimum time for the beetle to travel from point A to point B: 16 minutes

2. Number of different solutions: 1
