The distance traveled varies directly with the time spent in motion when speed is held constant. If d represents the distance traveled and t represents time, which equation would represent this variation? If you travel 150 miles in 4 hours, what is the constant of variation? If you continue traveling at a constant speed, how long will it take to travel 200 miles? Round to the nearest tenth of an hour. about hours\",[{""content"":""We have a direct variation. Distance
