       (ii)  A car moving with a speed of 36 km per hour.

Answer 1

odometer measures the speed of an automobile
speed of scooter=300 m/min
speed of car =(36×1000)/60
=600 m/min
so car is moving faster

Answer 2

The odometer of an automobile measures the distance travelled by it.

a. Speed of scooter = 300m/min = 300m/60s = 5ms-1

b. Speed of car = 36 km/h = 36× 5/18 ms-1 = 10 ms-1

Thus, car is moving faster.
