The ratio of the speed of two cars is 5 : 4. If the first car covers a distance in 4 hours, how much time will the second car take for the same distance? दो कारों की गति का अनुपात 5 : 4 है। यदि पहली कार 4 घंटे में एक दूरी तय करती है, तो दूसरी कार उसी दूरी के लिए कितना समय लेगी?
A
5 hours (5 घंटे)
B
4.5 hours (4.5 घंटे)
C
6 hours (6 घंटे)
D
3.2 hours (3.2 घंटे)
