Hello !
<u>((new value - old value) / old value) × 100 </u>
((30.60 - 25.50) / 25.50) × 100
= (5.10/25.50) × 100
= 0.2 × 100
= 20
→ The rate of increase is 20%

A sled dog racer completed a race in 6 hours. Because of changes in the terrain, his average speed for the last 48 miles was twice as fast as his average speed for the first 12 miles. Which equation can be used to find r, his average speed in miles per hour, during the first 12 miles?
Answer:
24/25
20/29
Step-by-step explanation:
Trigonometry ratios:

where O is the side opposite to the angle, A is the side adjacent to the angle and H is the hypotenuse (longest side)
As angles A and C are complementary, this implies that side b is the hypotenuse and sides a and c are the legs of a right triangle.
Referring to the attached diagram:
sin(A) = O/H = a/b
cos(C) = A/H = a/b
Therefore, sin(A) ≡ cos(C)
If sin(A) = 24/25 , the value of cos(C) = 24/25
If cos(A) = 20/29, the value of sin(C) = 20/29
