Akriti is travelling at a speed of 54 km/h on a highway, while Dushyant is travelling at a speed of 81 km/h. What is the difference in their speeds, in meters per second?
Answer & explanation
Correct answer: option 4
Akriti = 54 km/h
Dushyant = 81 km/h
Difference = (81 - 54) = 27 × \(\frac{5}{18}\) = 7.5 m/sec
