Question:

A man is training to run five miles. During the first week, he ran 3.7 miles. During the second week, he could run 13% farther. How many more miles will he have to run to reach his goal?

A 0.82
Explaination

First, calculate 13% of 3.7: $3632_w133_h14.png$ miles
Next, add this to the distance he could already run: 3.7 + 0.48 = 4.18 miles
Finally, subtract this number from his goal: 5 miles – 4.18 miles = 0.82 miles
