Recall your d = rt, or distance = rate * time
notice, the time he took to cover 63 miles with the wind, is the same amount of time he took against it with 51 miles only, let's say, he took "t" hours long
and he was cycling at a rate of "r"
thus

solve for "r"
Answer:
19/18
Step-by-step explanation:
The GCF of 9, 3, and 18 is 18.
Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.
9 * 2 = 18
1 * 2 = 2
2/18
3 * 6 = 18
6 * 2 = 12
12/18
5/18
Add all three fractions together:
12/18 + 5/18 + 2/18 = 19/18
The correct answer should be c if not mistaken
