Answer 1

Problem Analysis

We are given that the distance between two cities is 240 km. An automobile and a bus start simultaneously in the same direction from one city towards the other. The automobile has a speed of 80 km/h, and the bus has a speed of 56 km/h. We need to find the distance between them after 2 hours.

Solution

To find the distance between the automobile and the bus after 2 hours, we need to calculate the distance each of them has traveled in that time.

The distance traveled by the automobile can be calculated using the formula:

Distance = Speed × Time

Substituting the given values, we have:

Distance traveled by the automobile = 80 km/h × 2 hours

Similarly, the distance traveled by the bus can be calculated using the same formula:

Distance traveled by the bus = 56 km/h × 2 hours

Adding the distances traveled by the automobile and the bus will give us the total distance between them after 2 hours.

Let's calculate the distances:

Distance traveled by the automobile = 80 km/h × 2 hours = 160 km Distance traveled by the bus = 56 km/h × 2 hours = 112 km Adding these distances, we get:

Total distance between them after 2 hours = 160 km + 112 km = 272 km

Therefore, the distance between the automobile and the bus after 2 hours will be 272 km.

I hope this helps! Let me know if you have any further questions.
