4) 28:2=14 км.ч скорость 2ой группы

Answer 3

Calculation of the Speed of the Second Group

To calculate the speed of the second group, we need to determine the distance traveled and the time taken by the group.

The first group traveled from the village of Грибное (Gribnoye) to the village of Ягодное (Yagodnoye) on foot along the riverbank at a speed of 4 km/h. They started at 10:00 AM and arrived at 5:00 PM, which means they traveled for 7 hours.

The second group traveled by boat and arrived at 12:00 PM. We need to find out how long they traveled.

To calculate the distance traveled by the first group, we can use the formula:

Distance = Speed × Time

For the first group: Distance = 4 km/h × 7 hours = 28 km

Now, let's calculate the time taken by the second group:

Time = Arrival Time - Departure Time

The second group departed at 10:00 AM and arrived at 12:00 PM, which means they traveled for 2 hours.

To calculate the speed of the second group, we can use the formula:

Speed = Distance / Time

For the second group: Speed = 28 km / 2 hours = 14 km/h

Therefore, the second group traveled at a speed of 14 km/h.
