He threw 15210 feet farther, or 182520 inches farther on her second try than her first. 5112(yards)-42(yards)=5070(yards), so she threw the softball 5070 yards farther on her second try than on her first try. Since 1 yard=3 feet, we can convert 5070 yards to 5070*3=15210 feet. 1 yard is also equal to 36 inches (1 foot=12 inches), so 5070 yards=5070*36=182520 inches.
