Distance = Rate * Time or, for our purposes Time = Distance/Rate Time = 35 mile/35 mph = 1 hour
Distance = rate x time; d=rt In this case distance is in miles, rate is in miles/hr (mph) and time would be hours. 35miles=45miles/hr x t divide both sides of this equation by 45 mph t=35miles/45mph=7/9 hour or to the second, 46 minutes 40 seconds.
