Answer:
1,250 km
Step-by-step explanation:
40% can be expressed as a decimal by dividing by 100
[tex]40\% = \dfrac{40}{100}\\\\\textrm{If 40\% of X = 500, we can express this fact by:}\\\\\dfrac{40}{100}X = 500\\\\\\\textrm{Multiply both sides by $\dfrac{100}{40}$:}\\\\\dfrac{40}{100}X \cdot \dfrac{100}{40} = 500 \dfrac{100}{40} \\[/tex]
[tex]X = 1,250 km[/tex]
