If a car covers a distance of 360 km in 4 hours, what is its speed in meters per second (m/s)?
A20 m/s
B25 m/s
C30 m/s
D90 m/s
Explanation
First, calculate speed in km/h using Speed = Distance / Time = 360 / 4 = 90 km/h. To convert km/h to m/s, multiply by 5/18. Speed in m/s = 90 × (5/18) = 5 × 5 = 25 m/s.
