Step-by-step explanation:
25% is a quarter
therefore a quarter of 9 is
0.25×9

X=-b/2a=4/14=2/7
Plug this value back into the function to find the corresponding Y value
Time = t
<span>vf t = 260 </span>
<span>vp t = 320 </span>
<span>so </span>
<span>260/vf = 320/(vf+15) </span>
<span>320 vf = 260 vf +260(15) </span>
<span>60 vf = 390 </span>
<span>3 vf = 39 </span>
<span>vf = 13 km/hour
