Answer 3

Problem Analysis

The problem states that a driver traveled from the city of Totma to the city of Vologda in 3 hours at a speed of 72 km/h. On the return trip, the driver took 4 hours. We need to determine how much the driver reduced their speed.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Let's assume that the distance between Totma and Vologda is the same for both the forward and return trips. Let's call this distance "d".

For the forward trip: - Speed = 72 km/h - Time = 3 hours

Using the formula, we can calculate the distance: 72 km/h = d / 3 hours

Simplifying the equation, we find: d = 72 km/h * 3 hours = 216 km

For the return trip: - Time = 4 hours

Using the formula, we can calculate the speed: Speed = Distance / Time Speed = 216 km / 4 hours

Simplifying the equation, we find: Speed = 54 km/h

Therefore, the driver reduced their speed by 18 km/h on the return trip compared to the forward trip.

Conclusion

The driver reduced their speed by 18 km/h on the return trip compared to the forward trip.
