The ratio of the walking speeds of A and B is 3 : 5.
The ratio of the walking speeds of A and B is 3 : 5. If B takes 18 minutes to cover a certain distance, how much time will A take to cover the same distance?
A और B की चाल का अनुपात 3 : 5 है। यदि B को एक निश्चित दूरी तय करने में 18 मिनट लगते है, तो A को समान दूरी तय करने में कितना समय लगेगा?
Detailed Solution & Logic
Correct Answer:
30 min
Walking speed ratio of A and B = 3 : 5
Time is inversely proportional to speed.
Time ratio = 5 : 3
Given:
B takes 18 minutes.
Let A’s time = T
Using ratio:
$\dfrac{T}{18} = \dfrac{5}{3}$
$T = 18 \times \dfrac{5}{3} = 30$
