Answer 2

Calculation of Travel Time

To calculate the travel time between the village and the city, we need to consider the distance and the speeds at which the person traveled.

The distance between the village and the city is given as 144 km.

The person traveled to the city on a bus with a speed of 36 km/h, and returned to the village by car with a speed of 72 km/h.

To calculate the travel time, we can use the formula:

Time = Distance / Speed

Let's calculate the travel time for each leg of the journey.

1. Traveling to the city: - Distance: 144 km - Speed: 36 km/h - Time = 144 km / 36 km/h = 4 hours

2. Returning to the village: - Distance: 144 km - Speed: 72 km/h - Time = 144 km / 72 km/h = 2 hours

Therefore, the person spent 4 hours traveling to the city and 2 hours returning to the village.

Please note that these calculations assume a constant speed throughout the journey and do not account for factors such as traffic or breaks.
