To calculate the calories burned by walking for 4 hours at 2 mph for a 150-lb person using the formula 240h, we get 240 calories/hour multiplied by 4 hours, which equals 960 calories.

Step-by-step explanation:

The number of calories burned by a 150-lb person walking at 2 mph can be represented by the expression 240h, where 'h' represents the number of hours spent walking. To determine the calories burned by walking for 4 hours, we multiply 240 by 4:

• Calories burned = 240 calories/hour × 4 hours = 960 calories

Thus, the correct answer is (a) 960 calories.
