Two cyclists start from the same place to ride in the same direction. ...
Solution:
Let's assume that Aflatoon and Bablajoon meet after t hours from the time Aflatoon starts.
Distance covered by Aflatoon in t hours = 8t km
Distance covered by Bablajoon in (t-2) hours = 10(t-2) km
Distance between them = 5 km
As they are travelling in the same direction, we can subtract the distance covered by Aflatoon from that of Bablajoon.
10(t-2) - 8t = 5
10t - 20 - 8t = 5
2t = 25
t = 12.5 hours
Hence, Aflatoon and Bablajoon will be 5 km apart in 12.5 hours from the time Aflatoon starts.
Let's calculate the time when they will be 5 km apart.
Time when Aflatoon starts = noon
Time taken by Aflatoon to be 5 km apart from Bablajoon = 12.5 hours
Therefore, time when Aflatoon and Bablajoon will be 5 km apart = 12.00 pm + 12.5 hours = 7.30 pm (same day)
Now, we need to calculate the time on the next day when they are 5 km apart.
Total time taken by Bablajoon to reach the 5 km point = 12.5 hours + 2 hours (time difference between Aflatoon and Bablajoon)
= 14.5 hours
Time when Bablajoon will be 5 km apart from Aflatoon = 2.00 pm + 14.5 hours = 4.30 am (next day)
Therefore, Aflatoon and Bablajoon will be 5 km apart at 7.30 pm (same day) and 12.30 am (next day). Hence, the correct option is B.
Let's assume that Aflatoon and Bablajoon meet after t hours from the time Aflatoon starts.
Distance covered by Aflatoon in t hours = 8t km
Distance covered by Bablajoon in (t-2) hours = 10(t-2) km
Distance between them = 5 km
As they are travelling in the same direction, we can subtract the distance covered by Aflatoon from that of Bablajoon.
10(t-2) - 8t = 5
10t - 20 - 8t = 5
2t = 25
t = 12.5 hours
Hence, Aflatoon and Bablajoon will be 5 km apart in 12.5 hours from the time Aflatoon starts.
Let's calculate the time when they will be 5 km apart.
Time when Aflatoon starts = noon
Time taken by Aflatoon to be 5 km apart from Bablajoon = 12.5 hours
Therefore, time when Aflatoon and Bablajoon will be 5 km apart = 12.00 pm + 12.5 hours = 7.30 pm (same day)
Now, we need to calculate the time on the next day when they are 5 km apart.
Total time taken by Bablajoon to reach the 5 km point = 12.5 hours + 2 hours (time difference between Aflatoon and Bablajoon)
= 14.5 hours
Time when Bablajoon will be 5 km apart from Aflatoon = 2.00 pm + 14.5 hours = 4.30 am (next day)
Therefore, Aflatoon and Bablajoon will be 5 km apart at 7.30 pm (same day) and 12.30 am (next day). Hence, the correct option is B.
