Answer 1

1) 4*3=12 (км) - расстояние между сёлами
2) 12:1=12 (км/ч)
Ответ: на велосипеде скорость была 12км/ч.
 

Answer 2

Calculation of the Distance

To calculate the distance between the two villages, we can use the formula: distance = speed × time.

Given that the pedestrian walked at a speed of 4 km/h for 3 hours, we can calculate the distance covered by the pedestrian as follows:

distance = speed × time = 4 km/h × 3 hours = 12 km.

Therefore, the distance between the two villages is 12 kilometers.

Calculation of the Bicycle Speed

To calculate the speed at which the pedestrian traveled on the bicycle, we can use the formula: speed = distance / time.

Given that the pedestrian spent 1 hour on the return journey, we can calculate the speed at which the pedestrian traveled on the bicycle as follows:

speed = distance / time = 12 km / 1 hour = 12 km/h.

Therefore, the pedestrian traveled on the bicycle at a speed of 12 km/h on the return journey.
