Question

the distance between two cities is 400000 meters. If the train travels at a speed of 80 kilometers per hours, how long will it take the train to travel from one city to the next

Answer 1

5 hours.

Explanation:

• If the train travels at a speed of 80 kilometers per hour, and a kilometer is equivalent to 1000 meters, then the train travels at a speed of
  `80*1,000=80,000m`
• Then, to reach the 400,000 meters, it will take
  `(400,000)/(80,000) =5`, 5 hours.
