15/x=75/100
15/x=3/4
times 4x both sides
4*15=3x
60=3x
divide both sides by 3
20=x
Hello!
You can use the Pythagorean Theorem to solve this
c is the hypotenuse
a and b are the legs
Put in the values you know
Square the numbers
Subtract 2.25 from both sides
Take the square root of both sides
b = 0.8
The answer is 0.8km
Hope this helps!
