It’s
a Race
Manish, Diana, Isebel, Ris, and Ji-Yeong are the five runners in a
\(400\) m race. Their friend cheered
them on and took a photo partway through the race. The photo shows the
following:
Isebel is in the lead.
Ji-Yeong has run farther than Ris, but not as far as
Manish.
Diana has two people ahead of her and two people behind
her.
Using the information given, determine the order of the runners
in the photo. Fill in the blanks in the list shown below.
The following five fractions represent the fraction of the course
that each runner had completed in the photo. \[\frac{2}{3}, \frac{5}{6}, \frac{3}{4},
\frac{1}{3}, \frac{1}{4}\] Which runner completed each fraction
of the course? Show your work using diagrams or equivalent
fractions.
