You can put this solution on YOUR website!
d=rt Start with the distance-rate-time equation


40=45t Plug in d=40 and r=45


40%2F45=t Divide both sides by 45.


8%2F9=t Reduce


So the solution is t=8%2F9 which approximates to t=0.889. This means that it will take about 0.889 hours (which is about 53.34 minutes) to travel 40 miles.
