Doug and Ken are meeting for lunch at Rodrigo's Mexican Restaurant. Doug's work place is 5 miles from the restaurant and Ken's work place is 7 miles from the restaurant. Both of them drive at the same rate and Doug takes t minutes to get there while Ken takes m minutes to get there. Which equation represents this information?

Doug and Ken are driving at the same rate but they are coming from different places, with different distances. Since Doug takes t minutes and he is traveling 5 miles, his equation will be t=5x with x being the rate. Since Ken takes m minutes and he is traveling 7 miles, his equation will be m=7x with x being the rate. The equation that represents their travel would be 7/m = 5/t = x.
