Answer 2

Given that,

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.

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