You want the time for each leg since you know the sum of these two times is 5 hours. The units tell you what to do. In the first leg you have distance = 100 miles, speed = s miles per hour and you want time in hours. Thus on the first leg
How long did the second leg take? The sum of the two times is 5 hours. Solve for s. Make sure you verify your answer. Penny
