4x²+2x-115.162049=0

That's it !

So x≈0.701838730514401 (this isn't the exact value, the number being irrationnal)

It's 5*500,000/100=$25,000

Example: It took me 3 hours to run 15 km: so my average velocity (v) is equal to: $$v=\frac {15}{3}=5$$

So my average velocity is equal to 5 km/h

4^2x+1=8

4^2x=7

2x=log₄(7)

x= $$\frac{\log_4(7)}{2}$$

velocity=distance/time

You have to convert 100 yards into km, 52 s into hours, then use this formula.
