6th Grade Itinerary Problems Using Ratios: Problem 1

Problem: On Rose's way to school, there are three sections: uphill, flat, and downhill. The distance of the journey being uphill to the distance of the journey being flat to the distance of the journey being downhill is 1:2:3. The time Rose spent walking each of the different sections is 4:5:6. Rose's uphill speed is 3 kilometers per hour. If the total distance from Rose's house to her school is 10 kilometers, how long did it take her in total to walk from her house to her school?
