DI on Time and Distance 

A chunk of Questions is asked from Data Interpretation in the Quantitative Aptitude Section of banking exams.  In this study note we will discuss DI (Data Interpretation)  based on Time and Distance which are frequently asked in various competitive exams.

Basic Concept of speed ,Distance and time

The basic equation that will help you in solving time and speed sums is:

Speed = Distance / Time

It follows that:

Distance = Speed × Time

Time = Distance ÷ Speed

E) None of these

Solution: 
Distance = 628-434 = 194 km

Speed = 194/170 *60 = 68.47 kmph
option -c

Question 3: How much time does the train takes to reach Kanpur after departing from Aligarh?

Question 4: If out of 400 passengers who boarded the train from Anant Vihar, 200 passengers got down at Aligarh. Then find the ratio between the number of passengers who travelled between Aligarh- Kanpur and the number of passengers who boarded the train from Allahabad.
A) 400:203
B) 251:203
C) 651:203
D) 451:203
E) None of these
Solution:

Total passengers travelling from Aligarh-Kanpur = 400-200+251 = 451

Hence ratio => 451:203
