Question

hank is working in a silver mine 10ft below the surface. he descends until he reaches a point 57ft below the surface. how many feet does hank descend?

Answer 1

Depth of Hank descends = The point he reached - the point where he worked initially

                                          = 57 - 10

                                          = 47 ft

Hence, Hank descends 47 ft.
