This is a pythagorean theorem problem
When solving for the sides of a right triangle... a^2 + b^2 = c^2
Therefore, 7^2 + b^2 = 25^2
b^2 = 25^2 - 7^2 = 576
b = sqrt(576) = 24 
Answer: A 24

Answer:
1 2/9 minutes faster
Step-by-step explanation:
Take the larger number and subtract the smaller number
8 5/9 minutes - 7 1/3 minutes
Get a common denominator
8 5/9 - 7 1/3 *3/3
8 5/9 - 7 3/9
1 2/9 minutes faster
