Answer:
The answer is below
Explanation:
The question is not complete, the complete question is in the form of: David is choosing between two exercise routines. In Routine #1, he burns 20 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns calories 38 walking. He then runs at a rate that burns 8.5 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2? Use for the number of minutes spent running, and solve your inequality for .
Answer:
Let us assume that the number of minutes spent running is t minute. The equation that represents the total calories burnt for routine 1 is given as:
20 + 10.5t
While the total calories burnt for routine 2 is given as:
38 + 8.5t
Since Routine #1 burn at most as many calories as Routine #2, hence it can be represented by the inequality
20 + 10.5t < 38 + 8.5t
Solving the inequality:
10.5t - 8.5t < 38 - 20
2t < 18
t < 9 minutes
For routine 1 to burn at most as many calories as routine 2, the time spent running must be less than 9 minutes
David should run for less than or equal to (W2 - W1) / (R1 - R2) minutes for the calories burned in Routine #1 to be at most equal to that of Routine #2. W1, W2, R1, and R2 represent the number of calories burned walking and running rate in each routine, respectively.
The question doesn't provide specific figures for the amount of calories burned through walking or running in either routine. Therefore, for our purposes, let's denote the number of calories burned walking in Routine #1 and #2 as W1 and W2 respectively, and the rate of calories burned per minute running as R1 and R2 respectively.
If x represents the time (in minutes) David spends running, the total number of calories burned in Routine #1 would be W1 + R1*x, and for Routine #2 it would be W2 + R2*x.
David would burn at most as many calories with Routine #1 as he would with Routine #2 when W1 + R1*x ≤ W2 + R2*x. To solve this inequality for x, you would perform the following steps:
