1.72 because rocks 1 and 2 add up to 44.58 46.3-44.58=1.72
Answer: 24.49 or 24.5 if rounded.
Step-by-step explanation: We have to use the pythagorean theorem of course...
a² + b² = c²
15² + 20² = c²
225 + 400 = c²
600 = c²

c = 24.49 (If we round to the nearest tenth then the answer is 24.5)
1/2=4/8
4/8 less than 5/8
Good Luck!
