Answer:
Jogging = 10 hours
Swimming = 7 hours
Cycling = 3 hours
Step-by-step explanation:
J = Hours jogging
S = Hours swimming
C = Hours cycling
Since jogging is the activity that burns the most calories, we should maximize the number of hours jogging:
Therefore, the man should jog for 10 hours.
Since swimming is the activity that burns the second most calories, we should maximize swimming hours:
In order to maximize the number of calories burn, the man should go jogging for 10 hours, swimming for 7 hours and cycling for 3 hours.

Step-by-step explanation:
15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to gallons, and the total volume increases to gallons.
To get a concentration of 8% in this diluted solution, we add gallons of water such that
Solve for .
To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
