2) 12 + 4 = 16 км/ч увеличил скорость на обратный путь
3) 48 : 16 = 3 часа потратит на обратный путь

Answer 2

Calculation of Time for the Return Journey

To calculate the time the cyclist will spend on the return journey, we need to consider the following information:

- The cyclist traveled from the village to the city in 4 hours at a speed of 12 km/h. - The cyclist's speed on the return journey will be reduced by 4 km/h.

To find the time for the return journey, we can use the formula:

Time = Distance / Speed

Let's calculate the time for the return journey step by step:

1. Calculate the distance traveled by the cyclist from the village to the city using the formula:

Distance = Speed × Time

Distance = 12 km/h × 4 hours = 48 km

2. Calculate the time for the return journey using the formula:

Time = Distance / Speed

Distance = 48 km Speed = 12 km/h - 4 km/h = 8 km/h

Time = 48 km / 8 km/h = 6 hours

Therefore, the cyclist will spend 6 hours on the return journey.
