Solution
Verified by Toppr

#### Speed of car = $$12 \ m s^{-1}$$Speed of scooter = $$36 \ km h^{-1}$$Since, $$1 \ km = 1000 \ m$$and, $$1 \ hr = 3600 \ sec$$$$\therefore$$ Speed of scooter = $$36 \ km/hr = \dfrac{36\times 1000}{3600} \ m/s$$ = $$10 \ ms^{-1}$$Hence, the car travels faster than the scooter.
