Answer:
2 is a number and "twice a number" means multiply by 2.
Act like it's a rectangle. The height is 10 because 7+3=10 and the length it 27. Multiply them for the are and you get 270 in. Then multiply 6x7=42 because that's the are of the space that is missing from the imaginary rectangle. Multiply by 2 (84 in.) because there are 2 missing spaces and subtract from 270= 186 inches is your answer.
The answer should be 3 hours and 45 minutes if i did the math in my head correctly
I think if I do this correctly, the answer is x<-1
