Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
Step-by-step explanation:
Given,
Calories burned in Routine 1 = 15.5 calories per minute
Let,
t represents the number of minutes spent running.
Total calories burned = T
T = 15.5t Eqn 1
Calories burned in Routine 2 = 22 calories walking + 12.75 per minute
T = 12.75t + 22 Eqn 2
For burning more calories in Routine 1;
Eqn 1 > Eqn 2
Dividing both sides by 2.75
Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
