Directions: Answer the question based on the information given below:
Given below Pie chart shows the distribution of distance traveled by five different trains (Rajdhani Express, Shatabdi Express, Train 18, Maharaja Express, and Vivel Express out of a total distance of 3200 km.
Table given below shows the average speed and time taken by these five trains to cover the distance.
Note: Some values in the pie chart and table are missing. You have to calculate those missing values and answer the questions accordingly.
Consider all values in positive integers only.
| Trains | Speed (in km per hour) | Time (in hours) |
| Rajdhani Express | --- | 9 |
| Shatabdi Express | --- | 5 |
| Train 18 | 64 | 10 |
| Maharaja Express | 120 | --- |
| Vivek Express | --- | 20 |
A train, which is at a distance of 2400 km from Vivek Express starts approaching Vivek Express at a speed of x kmph, after 5hours from the start of the train, Vivek Express also starts to move towards the train at its normal speed. If they meet after 6 hours after the movement of Vivek Express, then find the value of x (in kmph).
