Problem Analysis

We are given the speeds of two trains, one traveling from St. Petersburg to Moscow and the other traveling from Moscow to St. Petersburg. We need to find the distance between the trains at different time intervals.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's calculate the distances between the trains at different time intervals.

a) One hour after the express train departs: The express train has a speed of 82 km/h. After one hour, it would have traveled a distance of 82 km.

b) Three hours after the freight train departs: The freight train has a speed of 48 km/h. After three hours, it would have traveled a distance of 48 × 3 = 144 km.

c) Five hours after the express train departs: The express train has a speed of 82 km/h. After five hours, it would have traveled a distance of 82 × 5 = 410 km.

Answer

a) One hour after the express train departs, the distance between the trains is 82 km. b) Three hours after the freight train departs, the distance between the trains is 144 km. c) Five hours after the express train departs, the distance between the trains is 410 km.
