Question

Велосипедист ехал 2 ч со скоростью 11.6 км/ч и 4 ч со скоростью 10.5 км/ч. Сколько километров проехал велосипедист за все это время?"

Answer 1

1) 2*11.6=23.2 км за первые два часа
2) 4*10.5=42 км за следующие 4 часа
3) 42+23.2=65.2 км проехал всего
Ответ: 65.5 км

Answer 2

Calculation of the Distance Traveled by the Cyclist

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

The first time interval is 2 hours, during which the cyclist traveled at a speed of 11.6 km/h. To find the distance covered during this time, we can use the formula:

Distance = Speed × Time

Substituting the given values, we have:

Distance1 = 11.6 km/h × 2 h

The second time interval is 4 hours, during which the cyclist traveled at a speed of 10.5 km/h. Using the same formula, we can calculate the distance covered during this time:

Distance2 = 10.5 km/h × 4 h

To find the total distance traveled by the cyclist, we need to add the distances covered during both time intervals:

Total Distance = Distance1 + Distance2

Let's calculate the distances:

Distance1 = 11.6 km/h × 2 h = 23.2 km

Distance2 = 10.5 km/h × 4 h = 42 km

Total Distance = 23.2 km + 42 km = 65.2 km

Therefore, the cyclist traveled a total distance of 65.2 kilometers during the given time intervals.
