A Digging Mistake 158 ft
B
An engineering company was hired to dig an underground tunnel directly from
point A to point B which was a distance of 1.4 miles. By mistake, however, they
tunneled from point A to point C. Then they tunneled from point to point B. If
tunneling costs about $120 million per mile, about how much money was wasted?
