Answer 1

11.5 км\ч -первая задача

2.5 ч - вторая задача

Answer 2

Calculation of the Cyclist's Speed:

To calculate the speed of the cyclist, we can use the formula: Speed = Distance / Time.

Given that the cyclist traveled a distance of 23 km in 2 hours, we can substitute these values into the formula to find the speed:

Speed = 23 km / 2 hours

Calculating this, we find that the speed of the cyclist is 11.5 km/h.

Calculation of the Pedestrian's Travel Time:

To calculate the time the pedestrian spent on the road, we can use the formula: Time = Distance / Speed.

Given that the pedestrian walked a distance of 10 km with a speed of 4 km/h, we can substitute these values into the formula to find the time:

Time = 10 km / 4 km/h

Calculating this, we find that the pedestrian spent 2.5 hours on the road.
