Answer:
[tex]1\dfrac{1}{4}km[/tex]
Step-by-step explanation:
Total Distance for the Race= 5km
If Nathan walked [tex]\frac{1}{4}[/tex] of the race.
Then:
[tex]\text{Distance walked by Nathan =}\dfrac{1}{4} X $Total Distance Of the Race\\=\dfrac{1}{4} X 5km\\=\dfrac{5}{4}\\=1\dfrac{1}{4}km[/tex]
Nathan walked a distance of 1.25km (in decimal fraction).
