Answer: I would choose Route B

Explanation: Let’s assume the circle in route A is equal to 100m then half of it would be 50m

For route B: First let’s find the diameter
d=circumference/pi
d=100/3.14 is approximately 32m

Now let’s look at the extra road to complete the destination:

Judging by the photo, I would cut the circle into 4 pieces and take one piece to look at. You can see that the extra road is 1/3 of the 1 piece.

Since the perimeter is 100m (assumption) so 1/4 of it will be 25m
And since the extra road is 1/3 of the 1 piece it means that it’s 1/3 of 25m

1/3 x 25 is approximately 8 and since there are 2 extra road 8 x 2=16m

Now we add the diameter with the extra we get 32+16=48m

And route B is shorter than route A by 2m so I would choose route B.

The tank is filled up at a total rate of 10 gal/min, and currently contains 500 gal of solution. It can hold up to 1000 gal, so it will take time t to fill it up completely:

500 gal = (10 gal/min) t

t = (500 gal) / (10 gal/min)

t = 50 min

In that time,

(8 gal/min) (50 min) = 400 gal of cola

and

(2 gal/min) (50 min) = 100 gal of cherry syrup

are added to the tank, so that when it's full, the tank contains 850 gal of cola and 150 gal of syrup.

So 150 gal of the total 1000 gal of solution is cherry syrup, or (150 gal)/(1000 gal) = 15/100 = 15% of the mixture.
