Quantitative Aptitude • Time, Speed & WorkEasy
A car covers 972 km in 6 hours. What is its speed in metres per second?
A. 90 m/s
B. 162 m/s
C. 583.2 m/s
D. 45 m/s✓ Correct Answer
💡 Solution & Explanation
Speed = distance ÷ time = 972 ÷ 6 = 162 km/h. To change km/h into m/s, multiply by 5/18 (because 1 km = 1,000 m and 1 hour = 3,600 seconds). So 162 × 5/18 = 45 m/s.
