Answer 2

Answer:

Q1 => Odometer measures the distance traveled by the automobile .

Q2=> the first will have speed of 5m/s and the second will have 10m/s .

Explanation:

Q2=> 1 ) 300m/ 60s = 5m/s .

2) 1km = 1000m and 1 hour =3600 s.

While converting km/s to m/s just multiply by 1000/3600 oor simply 5/18 ,

therefore 36 ×5/18 = 10m/s.
