Problem Analysis

We are given that two vehicles, a bus and a car, simultaneously start from two cities that are 400 km apart. The bus has a speed of 60 km/h, and the car has a speed of 90 km/h. We need to determine the distance between the two vehicles after 2 hours.

Solution

To find the distance between the two vehicles after 2 hours, we need to calculate the distance each vehicle has traveled in that time.

The distance traveled by the bus in 2 hours can be calculated using the formula: distance = speed × time. Substituting the given values, we have: distance_bus = 60 km/h × 2 h = 120 km.

Similarly, the distance traveled by the car in 2 hours can be calculated as: distance_car = 90 km/h × 2 h = 180 km.

Now, we can find the distance between the two vehicles by subtracting the distance traveled by the bus from the total distance between the cities: distance_between_vehicles = 400 km - 120 km = 280 km.

Therefore, after 2 hours, the distance between the bus and the car is 280 km.

Answer

The distance between the bus and the car after 2 hours is 280 km.
