Question

lee ran a mile in 7 1/3 minutes. his friend Sam ran the same mile in 8 5/9 minutes. how many minutes faster did lee run.

Answer 1

To calculate how many minutes faster Lee ran, we need to find the difference in the time it took for both Lee and Sam to run the mile.

First, convert 7 1/3 minutes to an improper fraction:
7 1/3 = (3*7 + 1) / 3 = 22/3 minutes

Next, convert 8 5/9 minutes to an improper fraction:
8 5/9 = (9*8 + 5) / 9 = 77/9 minutes

Now, find the difference between the two times:
22/3 - 77/9 = (22*3 - 77) / 9 = (66 - 77) / 9 = -11 / 9

So, Lee ran the mile 11/9 minutes faster than Sam.

To simplify this, divide 11 by 9: 11 ÷ 9 = 1.2222...

Therefore, Lee ran the mile approximately 1.22 minutes (or 1 minute 13.3 seconds) faster than Sam.
