Final answer:
The train, with an average speed of 6 km/h determined from traveling 252 km in 42 hours, will take 58.33 hours to complete a journey of 350 km.
Step-by-step explanation:
Calculating Time for a Train Journey
To calculate the time it will take for a train to complete a journey of 350 km, we need to first determine the average speed of the train from the information provided. The train travels 252 km in 42 hours. We use the formula for average speed, which is total distance divided by total time. Here's the computation step by step:
- Calculate the average speed: Average Speed = Total Distance / Total Time = 252 km / 42 h = 6 km/h.
- Determine the time taken to travel 350 km using the average speed: Time = Distance / Average Speed = 350 km / 6 km/h.
- Perform the division to find the time: Time = 58.33 hours.
The train will take 58.33 hours to complete a journey of 350 km, assuming it maintains the same average speed.
