Answer 1

Answer:

Answer 2

Answer : Object A travel Faster Than Object B .

Explanation:

Object A moves with a speed = 15 m/s

Object B moves with a speed = 20 km/h

Since the unit are different , we have to make them same .

let us convert 20 km/h in m/s

1 km = 1000 m

1 hour = 3600 sec

Then ,

= 20 × 1000 m

_________

3600 sec

= 20000

______

3600

= 5.55 m/s

Therefore Object A moves faster with a speed of 15 m/s than Object B with a speed of 5.55 m/s .
