Question

Michael has been training for a major marathon. In his first training session he was able to run 5 miles without stopping. Then in his fifth training session, he was able to run 5.6 miles without stopping. By what percent was Michael able to increase his running time?

Answer 1

Michael increased the distance he could run without stopping by 12 percent, which was calculated by taking the difference between his performance in his first and fifth training sessions (0.6 miles), dividing by the original distance (5 miles), and multiplying by 100.

Step-by-step explanation:

The question is asking to calculate the percent increase in the distance that Michael was able to run without stopping, from his first training session to his fifth training session. To find the percent increase, we use the formula: Percent Increase = ((New Value - Original Value) / Original Value) * 100. In Michael's case, the original value is 5 miles, and the new value is 5.6 miles.

• Calculate the difference: 5.6 - 5 = 0.6 miles
• Divide the increase by the original amount: 0.6 / 5 = 0.12
• Multiply by 100 to find the percentage: 0.12 * 100 = 12%

Therefore, Michael was able to increase the distance he could run without stopping by 12 percent from his first to his fifth training session.
