Information about 15 seconds is quite redundant. Say the third-place finisher ate T hot dogs and the winner ate W hot dogs.
(1) The winner consumed 24 more hot dogs than did the third-place finisher --> W=T+24 --> one equation two unknowns. Not sufficient.
(2) The winner consumed hot dogs at double the rate of the third-place finisher --> at double rate the winner would consume twice as many hot dogs, so W=2T --> one equation two unknowns. Not sufficient.
(1)+(2) We have two distinct linear equations with two unknowns, so we can get the single numerical values of T and W: T+24=2T --> T=24. Sufficient.
Answer: C.

1)
No hot dogs consumed by third placer=N3 = t *1/15
N3+24=t*r
insufficient.. we need to know the t or r
2)
N3= t*1/15
N1 = t*2/15
insuffcient
combined.
N1=2N3=N3+24
N3=24
N1=48
sufficient.
