A car travels with a speed 12 m s^-1, while a scooter travels with a speed 36 km h^-1. Which of the two travels faster?

Speed of car = 12 m s^-1

Speed of scooter = 36 km h^-1

1 km h^-1 = $\dfrac{\text{5}}{\text{18}}$ m s^-1

36 km h^-1 = 36 x $\dfrac{\text{5}}{\text{18}}$ = 10 m s^-1

So speed of scooter = 10 m s^-1

So car travels faster than scooter; since speed of car is more than that of scooter.
