Answer:
25
Step-by-step explanation:
Step 1: Given data
Circumference of the running track (c): 400 m
Total distance completed during the race (d): 10 km
Step 2: Convert "d" to meters
We will use the conversion factor 1 km = 10³ m.
10 km × (10³ m/1 km) = 10⁴ m
Step 3: Calculate the number of laps to be completed (n)
We will use the following expression.
n = d/c
n = 10⁴ m/400 m
n = 25
