Answer:
x = 33.33 kilometers
Step-by-step explanation:
you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.
[tex]\frac{percent}{base} =\frac{rate}{100}[/tex]
[tex]\frac{5}{x}=\frac{15}{100}[/tex] ; cross multiply.
15x = 500
x = 33.33 kilometers
therefore, the race is 33.33 kilometers.
