The ratio of the speed of two cars is 5:4. If the first car covers a distance of 200 km in 2 hours, what is the speed of the second car? दो कारों की गति का अनुपात 5:4 है। यदि पहली कार 2 घंटे में 200 किमी की दूरी तय करती है, तो दूसरी कार की गति क्या है?
A
60 km/h (60 किमी/घंटा)
B
80 km/h (80 किमी/घंटा)
C
100 km/h (100 किमी/घंटा)
D
120 km/h (120 किमी/घंटा)
or press Space / Enter
Correct Answer 80 km/h
Explanation
Speed of 1st car = 200/2 = 100 km/h. Since ratio is 5:4, 5 units = 100, then 1 unit = 20. Speed of 2nd car = 4 * 20 = 80 km/h.
