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?

1 answer

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.
