The world's tallest mountain is Mount Everest. On May 5, 1999, it was found to be 7 feet taller than it was previously thought to be. Before this date, Everest was thought to be 29,028 feet high. That height was
determined by B. L. Gulatee in 1954. The first measurement of Everest was in 1852. At that time the height was
thought to be 29,002 feet. What is the difference between the current height of Everest and the height measured
in 1852?
