A person travels from one place to another at 180 km/h and returns to the starting point by the same route at 240 km/h. If the total time taken is 6 hours, then find the distance between the two places.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 617.14 km.
Let D be the distance between the two places
We know that,
Time = Distance/Speed
⇒ D/180 + D/240 = 6
⇒ 4D/720 + 3D/720 = 6
⇒ 7D/720 = 6
⇒ 7D = 4320
⇒ D = 617.14
Hence, the distance between the two places will be 617.14 km
