Answer:

$\simeq 820 feet$

Step-by-step explanation:

He has asked me to move the finish line 0.25 km forward

Now,

we know that

1 km = 0.621371 mile

⇒ 0.25 km = $0.25 \times 0.621371$ mile

= $0.25 \times 0.621371 \times 1760 \times 3$ feet

(since 1760 yards = 1 mile and 3 feet = 1 yard)

= 820.20972 feet

$\simeq 820 feet$ . (Answer)
