Question

a running track has circumference of 400m. How many laps of the track should be completed during a 10km race

Answer 1

Answer:

25

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
