Study the following line chart carefully and answer the questions given below:
Below the pair of five trains are given. The sum of length of each pair and the time taken by trains in each pair to cross each other when travelling in opposite direction is given in the line graph.
Length (in decameter) and Time (in sec.) taken to cross each other when travelling to opposite direction. (1 decameter = 10 meter)
86 seconds
To determine the time taken by train A to pass train C when they are traveling in the same direction, we must first understand the concepts and use the given data effectively.
Step-by-Step Solution:
Conclusion: After performing these calculations, it was determined that the time taken by train A to pass train C while traveling in the same direction is 86 seconds.
Knowing these steps, you may be able to solve such problems effectively for any similar pair of data provided in other questions.
