Jacob threw a rock into a lake from a bridge 124 feet above the river's surface. The rock sinks 81 feet below the river’s surface. What is the distance between the elevations?

Answer 1

To find the distance between the elevations, we need to add the distance above the river's surface (124 feet) and the distance below the river's surface (81 feet).

124 feet + 81 feet = <<124+81=205>>205 feet

Therefore, the distance between the elevations is 205 feet.
