Direction: The line graph shows the distance covered by different trains in km and the data in the table shows the time taken by different trains to cover the distance (in hours). Time taken by different trains in hours

Train	Time
\[{{T}_{1}}\]	30 hours
\[{{T}_{2}}\]	9 hours 40 minutes
\[{{T}_{3}}\]	17 hours 30 minutes
\[{{T}_{4}}\]	-
\[{{T}_{5}}\]	21 hours 36 minutes
\[{{T}_{6}}\]	-
\[{{T}_{7}}\]	-

 

If the time taken by train \[{{T}_{7}}\] is \[\frac{7}{10}\] the time taken by train \[{{T}_{1}}\] then what will be the difference between the speed of train \[{{T}_{7}}\] and the speed of train \[{{T}_{1}}\]?

A)  \[10\frac{10}{21}kmph\]

B)  \[13\frac{5}{21}kmph\]

C)  \[6\frac{2}{7}kmph\]

D)  \[14\,\,kmph\]

E)  \[\frac{5}{21}\]
