The cyclist traveled from the village to the city for 4 hours at a speed of 12 km / h. How much time did he spend on the return journey along the same road if he increased the speed by 4 km / h.

1) Let’s calculate the distance from the village to the city, which the cyclist traveled: 12 • 4 = 48 (km);
2) Find out the new (increased) speed of the cyclist: 12 + 4 = 16 (km / h);
3) Determine how much time the cyclist will spend on the return journey if he increases the speed: 48: 16 = 3 (h).
Answer: a cyclist with an increased speed will spend 3 hours on the way back.
