Distance zone reach: PE Power Protection practice question

A 138 kV transmission line is 42 mi long, with a positive-sequence impedance of 0.80 Ω/mi at an angle of 84°. The phase-distance relay at one end is fed from 800:5 CTs and from wye-connected VTs rated 138 kV/√3 : 115/√3 V. Zone 1 is set to 80% of the line impedance. The zone 1 reach in secondary ohms is most nearly:
