Answer 1

1).70 : 7=10 км/ч -1 день
2).60 : 5=12 км/ч -2 день
3).48 : 6=8 км/ч -3 день
4).70+60+48=178 км-прошли лыжники за 3 дня 

Answer 2

Calculation of Speed and Distance for Each Day

To calculate the speed and distance for each day, we can use the formula:

Speed = Distance / Time

Let's calculate the speed and distance for each day based on the given information:

- First day: They walked for 7 hours and covered a distance of 70 km. - Speed on the first day = 70 km / 7 hours = 10 km/h - Distance covered on the first day = 70 km

- Second day: They walked for 5 hours and covered a distance of 60 km. - Speed on the second day = 60 km / 5 hours = 12 km/h - Distance covered on the second day = 60 km

- Third day: They walked for 6 hours and covered a distance of 48 km. - Speed on the third day = 48 km / 6 hours = 8 km/h - Distance covered on the third day = 48 km

Overall Distance Covered

To calculate the overall distance covered by the skiers in three days, we can simply add up the distances covered on each day:

Total distance covered = Distance on the first day + Distance on the second day + Distance on the third day Total distance covered = 70 km + 60 km + 48 km = 178 km

Therefore, the skiers covered a total distance of 178 km in three days.
