An ironman triathlete is going to be riding his bike for 4 hours. he plans on taking 3 bottles of his favorite sports beverage (20 oz/bottle) to consume during the ride. his beverage contains 110 mg of sodium per 8 oz. how many milligrams of sodium will he be consuming per hour during his ride?

206.25 mg of sodium per hour.
The triathlete will drink 3 bottles of 20oz drinks (3*20 = 60oz total). There is 110 mg per 8 oz serving. 60/8=7.5 servings. 110 mg per serving is 110*7.5= 825 total mg sodium. there are 4 hours to divide the sodium by. 825/4=206.25mg sodium

B

Step-by-step explanation:

Constant of proportionality can be calculated by two point slope formula, slope=(y2-y1)/(x2-x1)=(64-40)/(40-25)=24/15=8/5=1.6
