Answer:

  7h +11r = 350

Step-by-step explanation:

Let h and r represent minutes of hiking and running, respectively. Then calories burned by a 150-lb person doing these activities will total 350 when ...

  7h +11r = 350

_____

7 calories per minute are burned by hiking, so 7h will be the calories burned by hiking h minutes.

11 calories per minute are burned by running, so 11r will be the calories burned by running r minutes.

The total of calories burned in these activities will be 7h+11r, and we want that total to be 350.
