The table below shows the finishing times for four runners in a 100-meter race. In what order did the runners cross the finish line?

The finishing order is the fastest to the slowest. And that means we’ll be ordering these values from least to greatest. Three of the runners finished in 13 seconds, and one runner finished in 14 seconds. We need to look at the tens place to find out which runner was the fastest.

Charlotte has an eight in the tenths place, Isabella has a nine in the tenths place, and Jennifer has a seven in the tenths place. The seven in the tenths place is the smallest value. 13.79 is the smallest time. Jennifer crossed the finish line first after 13.79 seconds.

After that, we can compare Charlotte and Isabella. Charlotte finished in 13.84 of a second. Isabella finished in 13.97. Eight in the tenths place is smaller than nine in the tenths place, making Charlotte the second-place finisher. Isabella comes next and finally Elizabeth, who finished in 14.31 of a second. By comparing their racing times, we found that the order the runners crossed the finish line is this: Jennifer, Charlotte, Isabella, Elizabeth.
