Here is the problem:
Two brass monuments set on a shady sidewalk have a known, verified horizontal separation of 99.96 ft. A surveyor measures between the monuments with a tape and reads 99.99 ft at a temperature of 83 degrees Fahrenheit, holding a tension of 15 lb while the tape is fully supported.
The length (ft) of the surveyor's tape between the 0 and 100 marks while the temperature remains at 83 degrees Fahrenheit is most nearly:
A 99.95
B 99.97
C 100.03
D The question cannot be answered with the information given
Here is the solution:
99.96 x
------ = -----
99.99 100
x=99.97 ft
The correct answer is B
Can someone tell me why this solution works?
