Problem Analysis

We are given that a train needs to travel 1200 km in 16 hours. It is also mentioned that the train has already traveled the first 35% of the distance in 6 hours. We need to determine the speed at which the train should continue to travel in order to arrive at its destination on schedule.

Solution

To find the speed at which the train should continue to travel, we can use the formula:

Speed = Distance / Time

Let's calculate the remaining distance and time for the train to reach its destination.

The total distance the train needs to travel is 1200 km. Since the train has already traveled 35% of the distance, the remaining distance is:

Remaining Distance = Total Distance - Distance Traveled

Remaining Distance = 1200 km - (35% of 1200 km)

To calculate the remaining distance, we need to find 35% of 1200 km. Let's calculate that:

35% of 1200 km = (35/100) * 1200 km

Now, let's calculate the remaining distance:

Remaining Distance = 1200 km - (35/100) * 1200 km

Next, we need to calculate the remaining time for the train to reach its destination. The total time available is 16 hours, and the train has already traveled for 6 hours. Therefore, the remaining time is:

Remaining Time = Total Time - Time Traveled

Remaining Time = 16 hours - 6 hours

Now that we have the remaining distance and remaining time, we can calculate the speed at which the train should continue to travel:

Speed = Remaining Distance / Remaining Time

Let's substitute the values and calculate the speed.

Calculation

The remaining distance is calculated as follows:

Remaining Distance = 1200 km - (35/100) * 1200 km

The remaining time is calculated as follows:

Remaining Time = 16 hours - 6 hours

Finally, the speed at which the train should continue to travel is calculated as follows:

Speed = Remaining Distance / Remaining Time

Let's calculate the values:

Remaining Distance = 1200 km - (35/100) * 1200 km = 1200 km - 0.35 * 1200 km = 1200 km - 420 km = 780 km

Remaining Time = 16 hours - 6 hours = 10 hours

Speed = Remaining Distance / Remaining Time = 780 km / 10 hours = 78 km/h

Answer

Therefore, the train needs to continue traveling at a speed of 78 km/h in order to arrive at its destination on schedule.
