A man travelled from Tirupati to Tirumala at the speed of 20 km/h and walked back at the speed of 4 km/h. If the whole journey took 24 hours, then find the distance (in km) between Tirumala and Tirupati.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 80.
Let the distance between Tirupati and Tirumala = d km
So, d/20 + d/4 = 24
⇒ 6d/20 = 24
⇒ 6d = 480
⇒ d = 480/6 = 80 km
