Answer:
3 yards high
Step-by-step explanation:
Given the following data
Height of shorter diving board = 2 1/4 yards
If the taller diving board is 1 1/3 the height of the shorter diving board, then;
Height of taller diving board = 1 1/3 of 2 1/4
Height of taller diving board = 4/3 * 9/4
Height of taller diving board = 36/12
Height of taller diving board = 3 yards
Hence the taller board is 3 yards high
