You can put this solution on YOUR website!
+80+ km/hr = ( +80+ km ) / ( +1+ hr )
The units of the ratio are:
[ km ] / [ hr ] = [ km ] / [ hr ]
+80+%2F+1+=+527+%2F+t+
where +t+ is in hrs
----------------------------
Multiply both sides by +1%2At+
+80t+=+5278+
+t+=+65.975+
and
+.975%2A60+=+58.5+
and
+.5%2A60+=+30+
---------------------
It will take 65 hrs 58 min 30 sec
