Solution:
Let's break down the information given in the question to understand it better:
- A bullet train left for New York after x hours and y minutes.
- The train reached Canada after travelling for z hours and x minutes.
- The arrival time in Canada was y hours on the same day.
We need to find the possible values of x.
To solve this problem, we need to use the concept of time, distance, and speed. We know that the distance between New York and Canada is fixed. Let's assume it to be D.
We can calculate the speed of the bullet train using the formula:
Speed = Distance/Time
We know the time taken by the bullet train to travel from New York to Canada:
Time = (z + x)/60 hours
We can calculate the speed of the train using the above formula.
We also know the time at which the train reached Canada:
Time = y hours
Using the above information, we can calculate the distance travelled by the bullet train:
Distance = Speed * Time
Now, let's consider the possible values of x:
1. If the train left New York at exactly y minutes after x hours, then the time taken by the train to reach Canada would be:
Time = (x + z + (60 - y))/60 hours
Using the above formula, we can calculate the speed and distance travelled by the bullet train.
2. If the train left New York before y minutes after x hours, then the time taken by the train to reach Canada would be:
Time = (x + z + (60 - y))/60 hours
Using the above formula, we can calculate the speed and distance travelled by the bullet train.
Therefore, there are two possible values of x.
Hence, the correct answer is option 'B'.

From the given info we can say that z hour x minutes = y hour z minutes - x hour y minutes
60z+x = 60y+z - 60x - y
59z+61x= 59y..... (1)
Also, z hour x minutes < 24="" hour="" />
60z +X < 24="" ....="" />
here we have 2 linear equation but variable are there so kindly recheck the question as it cannot be solved .
Thanks by regards:- Shivaditya Dwivedi
if any doubth ask I will solved anyone of my edurev members
60z+x = 60y+z - 60x - y
59z+61x= 59y..... (1)
Also, z hour x minutes < 24="" hour="" />
60z +X < 24="" ....="" />
here we have 2 linear equation but variable are there so kindly recheck the question as it cannot be solved .
