36 km/h= 10m/s. car is faster then scotter because car travels with the speed of 12km/h and the scooter travels with the speed of10m/s

Answer 2

Speed of car is 12 m/s and speed of scooter is 36 km/h.

To find,

Which of the two travels faster.

Solution,

It means, we need to compare the speeds of car and the scooter. For comparison, we must have both speeds in same unit.

36\ km/h=\dfrac{36\times 1000\ m}{3600\ s}=10\ m/s36 km/h=3600 s36×1000 m=10 m/s

Now the speed of scooter is 10 m/s. So, it is clear that the car travels with the greater speed.
