Answer 1

Молодец. ответ правильный

Answer 2

Calculation of Distance Traveled by the Motorcyclists

To determine which motorcyclist traveled a greater distance, let's calculate the distance traveled by each of them.

The first motorcyclist traveled 80 km in 4 hours, which gives us a speed of 80 km / 4 hours = 20 km/h.

The second motorcyclist traveled 60 km in 4 hours, which gives us a speed of 60 km / 4 hours = 15 km/h.

Now, let's calculate the distance traveled by each motorcyclist:

- The first motorcyclist traveled for 4 hours at a speed of 20 km/h, so the distance traveled is 4 hours * 20 km/h = 80 km. - The second motorcyclist also traveled for 4 hours, but at a speed of 15 km/h, so the distance traveled is 4 hours * 15 km/h = 60 km.

Conclusion

Based on the calculations, the first motorcyclist traveled a greater distance, covering 80 km, while the second motorcyclist covered 60 km.

Therefore, the first motorcyclist traveled 80 km, which is 20 km more than the second motorcyclist.
