Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 20 km.
Given:
Raghu and raman start together to walk a certain equal distance at speed of 10 km/h and 8 km/h
Calculations:
Let the total distance be D
According to the question;
⇒ (D/8) - (D/10) = 30
⇒ (5D - 4D)/40 = 1/2
⇒ D = 20 km
