Answer 2

Answer: The answer is, 'Car'.

Explanation: Because,

           Here there is two metric unit systems;

'km/hr' and 'm/sec'.

  we have to change m/sec to km/hr (or) km/hr to m/sec.

Case-1. for changing 'm/sec' to km/hr, we have to multiply with "18/5".

Case-2. for changing 'km/hr' to m/sec, we have to multiply with "5/18".

Now, i want to proceed with case-1,

 converting car's speed from m/sec to km/hr => 12*18/5= 43 Km/hr.

in the question, speed of the scooter is '36 km/hr'.

CONCLUSION:- Finally car travells faster than scooter.

I hope it will helpful to you.
