You can put this solution on YOUR website!
d+=+rt
d+=+230
.
%281%2F2%29r%2A5t+=+Unknown
.
So, the second equation appears to be the first equation * 5/2.
.
%285%2F2%29%2A230=575
.
You can do a mental exercise to determine if that's the right answer.
It traveled 1/2 as fast, so in the same amount of time it would have traveled 1/2*230 = 115 miles.
But we're also told it travelled for 5 times as long: 5*115 = 575.
.
Done.
