\(V=\frac{s}{t},where\ V-speed,\ s-distance\ ,t-time\\\\ V=\frac{197.65miles}{3\frac{7}{20}h}=\frac{197.65}{\frac{67}{20}}=197.65*\frac{20}{67}=\frac{3953}{67}=59\frac{miles}{h}\\\\Answer\ is\ d.\)

\(s=197.65\ mi\\\\t=3\frac{7}{20}\ h=\frac{67}{20}\ h\\\\v=\frac{s}{t}\\\\therefore:\\\\v=\frac{197.65}{\frac{67}{20}}\ mph=197.65\cdot\frac{20}{67}\ mph=2.95\cdot20\ mph=\boxed{59\ mph}\\\\Answer:\boxed{(d)}\)
