Problem Analysis

To solve this problem, we need to find the time the tourist spent traveling by train. We know that the total distance traveled was 250 kilometers, and the tourist traveled by car for 2 hours at a speed of 46 kilometers per hour. The remaining distance was covered by train at a speed of 55 kilometers per hour. We need to find the time spent traveling by train.

Solution

Let's assume the time spent traveling by train is t hours.

We can calculate the distance traveled by car using the formula: distance = speed × time. Therefore, the distance traveled by car is 46 kilometers per hour × 2 hours = 92 kilometers.

The remaining distance traveled by train is the total distance minus the distance traveled by car: 250 kilometers - 92 kilometers = 158 kilometers.

We can calculate the time spent traveling by train using the formula: time = distance / speed. Therefore, the time spent traveling by train is 158 kilometers / 55 kilometers per hour = 2.8727 hours.

Rounding to the nearest hour, the tourist spent approximately 3 hours traveling by train.

Answer

The tourist spent approximately 3 hours traveling by train.

Explanation

The tourist traveled by car for 2 hours at a speed of 46 kilometers per hour, covering a distance of 92 kilometers. The remaining distance of 158 kilometers was covered by train at a speed of 55 kilometers per hour. Therefore, the tourist spent approximately 3 hours traveling by train.
