A person travels from one place to another at 60 km/hr and returns at 75 km/hr. If the total time taken is 6 hours, then find the total distance travelled.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 400 km.
Let the distance between the two places = D km
So, D/60 + D/75 = 6
⇒ 9D/300 = 6
⇒ D = 200
Total Distance = 200 + 200 = 400 km
