Question

Лыжник двигался 2 часа со скоростью 15 км/ч и 3ч со скоростью 14км/ч какое расстояние он преодолел за это время?

Answer 1

2*15=30 3*14=42 30+42=72 это же просто

Answer 2

Calculation of Distance Traveled by the Skier

To calculate the distance traveled by the skier, we need to find the total distance covered during the two different time intervals.

The skier traveled for 2 hours at a speed of 15 km/h and then for 3 hours at a speed of 14 km/h.

To find the distance traveled during the first interval of 2 hours at a speed of 15 km/h, we can use the formula:

Distance = Speed x Time

Substituting the given values, we have:

Distance1 = 15 km/h x 2 hours

To find the distance traveled during the second interval of 3 hours at a speed of 14 km/h, we can use the same formula:

Distance2 = 14 km/h x 3 hours

Now, we can calculate the total distance traveled by adding the distances from both intervals:

Total Distance = Distance1 + Distance2

Let's calculate the distances:

Distance1 = 15 km/h x 2 hours = 30 km

Distance2 = 14 km/h x 3 hours = 42 km

Total Distance = Distance1 + Distance2 = 30 km + 42 km = 72 km

Therefore, the skier traveled a total distance of 72 kilometers during the given time.
