Step-by-step explanation:
The problem statement tells you the function rule gives you H (the dependent quantity) as a function of t seconds. "t seconds" is the independent quantity.
everything seems to be correctly filled.
if you wanted confidence by confirmation: here, take some
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
