The first pump empties half the pond in 3 hours, so in 1/6 that time (1/2 hour), it empties (1/6)·(1/2) = 1/12 of the pond.
The second pump empties the other 5/12 of the pond in that half hour, so has a pumping rate of (1/2 h)/(5/12 pond) = (6/5 h)/pond.
The second pump could do the entire job alone in 1 hour and 12 minutes.

Answer:
x = 12
Step-by-step explanation:
The angle formed by two chords is half the sum of the intercepted arc angles.
m∠UST = ½ (mVL + mUT)
5x + 18 = ½ (66 + 8x − 6)
10x + 36 = 60 + 8x
2x = 24
x = 12
