Manav starts from a place A and reaches the place B in 29 hours. He travels 2/9 distance at the speed of 9 km/hr and the remaining distance at the speed of 12 km/hr. What is the distance between A and B?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 324 km.
The total time required to go from A to B = 29 hours
Let the total distance between A and B = 9x
Time = Distance/Speed
So, (2x/9) + (7x/12) = 29
⇒ 29x/36 = 29
⇒ x/36 = 1
⇒ x = 36
⇒ 9x = 9 × 36 = 324
Therefore, the distance between A and B is 324 km.
