Ahmedabad and Lucknow are 864 km apart. Ram starts from Lucknow toward...
Let Rahul’s and Ram's speed be a km/hr and Avinash’s speed be b km/hr.
Ram travelled 7.5a km and Rahul travelled 6a km before they met each other.
7.5 a + 6a = 864
a = 64 km/hr
Also when Rahul met Avinash,
7.25 a + 6.55 = 864
(7.25 x 64) + 6.55 = 864
5 = 400/6.5 km/hr
The time taken by Avinash to reach Ahmedabad from Lucknow = 864 x 6.5/400 = 14.04 hours
Hence, option 3.
Ahmedabad and Lucknow are 864 km apart. Ram starts from Lucknow toward...
To solve this problem, let's analyze the information given step by step:
- Distance between Ahmedabad and Lucknow: 864 km
- Starting time of Ram from Lucknow: 7 a.m.
- Starting time of Rahul from Ahmedabad: 8.30 a.m.
- Starting time of Avinash from Lucknow: 9.15 a.m.
- Rahul meets Ram at: 2.30 p.m.
- Rahul meets Avinash at: 3.45 p.m.
We need to find the time taken by Avinash to reach Ahmedabad.
Let's calculate the time taken by Rahul to meet Ram:
- Rahul meets Ram at 2.30 p.m., which means they have been traveling for 6 hours and 30 minutes.
- Since Rahul started at 8.30 a.m., Ram must have started 1.5 hours earlier at 7 a.m.
- Therefore, Ram has been traveling for 7 hours and 30 minutes.
Now, let's calculate the time taken by Avinash to meet Rahul:
- Avinash meets Rahul at 3.45 p.m., which means they have been traveling for 6 hours.
- Since Avinash started at 9.15 a.m., Rahul must have started 1.5 hours earlier at 7.45 a.m.
- Therefore, Rahul has been traveling for 7 hours.
Now, let's calculate the time taken by Avinash to reach Ahmedabad:
- Avinash meets Rahul at 3.45 p.m., which means they have been traveling together for 6 hours.
- Since Avinash started at 9.15 a.m., he has been traveling for 6 hours and 30 minutes.
- Therefore, Avinash takes a total of 6 hours and 30 minutes to reach Ahmedabad.
Converting the time to hours:
- 6 hours and 30 minutes is equivalent to 6.5 hours.
Therefore, the time taken by Avinash to reach Ahmedabad is 6.5 hours, which is option C) 14.04 hours.
