you see this sign on the road. a semi - truck pulls up next to you and the driver leans out the window, \hey, pal!\ he calls. \whats the height limit for that underpass?\
Answer
Explanation:
Step1: Interpret the sign
The sign shows "12'-6" which represents a height - measurement. The symbol ' stands for feet and " stands for inches.
Step2: Convert to a single - unit (inches)
1 foot = 12 inches. So 12 feet is 12×12 = 144 inches. Then add the 6 inches. 144+6 = 150 inches.
Answer:
12 feet 6 inches or 150 inches
