Joe Jump dives at the same angle as Jenny Jump and enters?

Question

the water 6 feet from the base of the wall. How high was the diving block from which Joe Jump jumped?

Answer 1

You have a right triangle similar to that of the previous question, but now the horizontal leg is 6 ft long, instead of 4 ft. So, all of the sides of Joe's triangle are 3/2 the length of those of Jenny's triangle, which means the distance he traveled is 5*3/2 = 7.5 ft.

Answer 2

The same height as it was when Jenny Jump Jumped!
