They can spend two days on the hike. The length of the route on the map is 78 km. On the first day they are going to walk for 6 hours, and on the second – 7 hours. How many kilometers will they walk every day if their speed is the same?

1) 6 + 7 = 13 (hour) – they will go in total;
2) 78/13 = 6 (km / h) – the speed at which they go all the time;
3) 6 * 6 = 36 (km) – will pass in the first day;
4) 6 * 7 = 42 (km) – will pass in the second day.
