The ratio of the speeds of two cars is 3 : 4. If the first car covers a distance of 150 km in 5 hours, find the speed of the second car. दो कारों की गति का अनुपात 3 : 4 है। यदि पहली कार 5 घंटे में 150 किमी की दूरी तय करती है, तो दूसरी कार की गति ज्ञात कीजिए।
A
35 km/hr (35 किमी/घंटा)
B
40 km/hr (40 किमी/घंटा)
C
45 km/hr (45 किमी/घंटा)
D
50 km/hr (50 किमी/घंटा)
or press Space / Enter
Correct Answer 40 km/hr
Explanation
Speed of 1st car = 150 / 5 = 30 km/hr. Ratio is 3 : 4. 3 parts = 30 km/hr -> 1 part = 10 km/hr. Speed of 2nd car = 4 * 10 = 40 km/hr.
