Answer:

188km

Hi there!!

I hope this answer helps.

Step-by-step explanation:

You can solve this with simple cross multiplication. (proportion)

so,

$25km \: = 4l \\ x = 30l \\ 25 \times 30 = 750 \\ 4 \times x \ \ = 4x \\ sinc \: we \:are \: looking \: for \: x \: you \: have \: to \: divid \: both \: sides \: by \: 4 \\ 750 = 4x \\ \frac{750}{4} = \frac{4x}{4} \\ \\ x = 187.5$

x = 187.5 which can be rounded to 188km
