Answer 3

Calculation of the Time Taken by the Train

To calculate the time taken by the train, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken for each segment of the journey and then add them together to find the total time.

1. The train traveled a distance of 560 km at a speed of 70 km/h. Using the formula, we can calculate the time taken for this segment:

Time = 560 km / 70 km/h = 8 hours.

2. The train traveled a distance of 240 km at a speed of 60 km/h. Using the formula, we can calculate the time taken for this segment:

Time = 240 km / 60 km/h = 4 hours.

Now, let's add the times for both segments to find the total time taken by the train:

Total Time = 8 hours + 4 hours = 12 hours

Therefore, the train was in transit for a total of 12 hours.

Please note that the above calculations are based on the given information and assume a constant speed throughout the journey.
