Rajan climbed to a height of 10 ft from the bottom of a climbing wall. He then climbed up an additional 5 ft.

Question

What must he do to return to the bottom of the climbing wall?

Answer 1

To return to the bottom of the climbing wall, Rajan must climb down the total distance he climbed up. Since he climbed up 10 ft and then an additional 5 ft, he must climb down a total distance of 10 + 5 = <<10+5=15>>15 ft.
