Question

If a 5 km race is approximately 3.1 miles, how many meters would you have to run to complete ahalf marathon (13.1 miles)

Answer 1

we know that

5 km race is approximately 3.1 miles

or

5,000 meters ----------> 3.1 miles

so

Applying proportion

Find out how many meters are 13.1 miles

5,000/3.1=x/13.1

solve for x

x=(5,000/3.1)*13.1

x=21,129 meters
