A steel tape with a cross-sectional area of 0.039cm2 and weighing 0.909kg has a length of 30.009m between the zero and the 30-m marks when supported throughout at 20C and subject to a tension of 5.5kg. This tape is used to measure a distance along a uniform 4% grade and is supported throughout during the measurement. The tension applied is 12kg. The temp of the tape is 2C. The measured slope distance is recorded as 381.615m. What is horizontal distance?
