Answer 2

Problem Analysis

We are given that a bus traveled 320 km in 1 hour. We need to determine how many kilometers a high-speed train will travel in 4 hours if it covers 70 km more than the bus each hour.

Solution

To solve this problem, we can use the following steps:

1. Calculate the distance the bus travels in 4 hours: 320 km/hour * 4 hours = 1280 km. 2. Calculate the additional distance the train covers each hour compared to the bus: 70 km/hour. 3. Multiply the additional distance by the number of hours the train travels: 70 km/hour * 4 hours = 280 km. 4. Add the additional distance to the distance traveled by the bus: 1280 km + 280 km = 1560 km.

Therefore, the high-speed train will travel 1560 km in 4 hours.

Answer

The high-speed train will travel 1560 km in 4 hours if it covers 70 km more than the bus each hour.
