Answer:
NO. Alex was wrong.
The total dive distance is 21 + 17 = 38 feet
Step-by-step explanation:
Alex was wrong because his direction of diving is from above the water through the surface of the water to under the water.
So his direction of travelling is not opposite but the same.
Therefore the total distance traveled by Alex = distance traveled from the diving board to the water surface + distance traveled from the water surface to down below the water
Distance traveled from the diving board to the water surface = 21 feet
Distance traveled from the water surface down below the water = 17 feet
Total distance traveled by Alex = 21 feet + 17 feet
= 38 feet.
Thus, Alex was wrong because the the total distance traveled by Alex was 38 feet.
