Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.
You start off with (x)+(3x)=3675, so you can find the value of x, so you combine to create 4x=3675. then you divide 3675 by 4 to get x=918.75. then you plug them into the equations to find your numbers.
so the numbers are 918.75, and 2756.25
1 hour = 60 minutes
66 miles / 60 minutes = 1.1 miles per minute
1.1 miles per minute x 10 minutes = 11 miles
I believe the answer is A.
