Quantitative Aptitude • Time, Speed & WorkEasy
A car covers 1,404 km in 6 hours. What is its speed in metres per second?
A. 65 m/s✓ Correct Answer
B. 234 m/s
C. 842.4 m/s
D. 130 m/s
💡 Solution & Explanation
Speed = distance ÷ time = 1,404 ÷ 6 = 234 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 234 × 5/18 = 65 m/s.
