| **A car travels the distance between two cities in 4.2 hours at some speed. How long will it take for a car to travel the same distance if its speed decreases 1.2 times?**

Recall the formula for travel time: t = S / v, where S is the distance traveled, and v is the speed. In this formula, t and v are inversely proportional, that is, if v increases, then t decreases and, conversely, if v decreases, then t increases. This means that if the speed of the car decreases by 1.2 times, then the travel time will increase by the same amount.

4.2 x 1, 2 = 5.04 (h).

Answer: if the car reduces its speed by 1.2 times, then it will cover this distance in 5.04 hours.
