Answer 1

1) 15+57=72
2) 72 на 3=216
3) 288 - 216= 72
ОТВЕТ: 72 километра

Answer 2

Calculating the Distance Between the Cyclist and the Motorcyclist

To calculate the distance between the cyclist and the motorcyclist after 3 hours, we can use the formula:

Distance = Speed × Time

Given: - Speed of the cyclist = 15 km/h - Speed of the motorcyclist = 57 km/h - Time = 3 hours

Using the formula, we can calculate the distance between them after 3 hours.

For the cyclist: Distance = 15 km/h × 3 h = 45 km

For the motorcyclist: Distance = 57 km/h × 3 h = 171 km

Total Distance Between Them After 3 Hours

The total distance between them after 3 hours can be calculated by adding the distances covered by the cyclist and the motorcyclist.

Total Distance = Distance covered by cyclist + Distance covered by motorcyclist Total Distance = 45 km + 171 km = 216 km

Therefore, the distance between the cyclist and the motorcyclist after 3 hours of starting their journey is 216 km.
