You can put this solution on YOUR website!
Use the distance formula: Distance = (Rate)(Time)
500 miles = (157.603)(t) [plug-in the values]
500/157.603=157.603t/157.603 [isolate the t-term]
3.172528=t
or
t=3.173 hours
.
Check by plugging all of the variables back into the original equation and solve:
D=rt
500=(157.603)(3.173)
500=500.074 [close enough]
