Answer 2

Calculation of Distance between Cities

To find the distance between the two cities, we can use the formula:

Distance = Speed x Time

Let's calculate the distance using the given information.

Given: - Speed of Train 1 = 60 km/h - Speed of Train 2 = 80 km/h - Time taken to meet = 7 hours

Using the formula, we can calculate the distance traveled by each train:

Distance1 = Speed1 x Time Distance2 = Speed2 x Time

Substituting the given values:

Distance1 = 60 km/h x 7 hours Distance2 = 80 km/h x 7 hours

Calculating the distances:

Distance1 = 420 km Distance2 = 560 km

Therefore, the distance between the two cities is 420 km (for Train 1) and 560 km (for Train 2).
