Answer:
x=6
Step-by-step explanation:
Step 1: Divide both sides by 17.
17x17=10217
x=6
3 feet is equal to 1 inch if she measured 3 inches to equal 9 feet
V = x/t = 4.5 mil / 3 h = 1.5 mph
Since, v = 1.5 mph (or we can say that v is constant), distance and time vary directly and the constant of variation is 1.5 mph.
