Answer:here we go
Step-by-step explanation:
12 miles a hour is 5 mins a mile
So the cube is 8 miles in perimeter
That would be 8×5 and 40 minutes around the cube
The perimeter of the cone is 18.85 so 18.85×5=94.25 and 94.25 minutes around the cone.
The rectangular prism is 16 miles in perimeter so 16×5=80 that's 80 minutes around the prism.
40+94.25+80=214.25 minutes and 3.57083... Hours total
