Answer 2

Answer:

We know that,

$1km \: {hr}^{ - 1} = 1000 \times \frac{1}{3600} m \: {s}^{ - 1}$

$= > 1km \: {hr}^{ - 1} = \frac{5}{18} m \: {s}^{ - 1}$

Therefore,

$= > 54km \: {hr}^{ - 1} =54 \times \frac{5}{18} m \: {s}^{ - 1}$

$= > 54km \: {hr}^{ - 1} = 3 \times 5m \: {s}^{ - 1}$

$= > 54km \: {hr}^{ - 1} = 15 m \: {s}^{ - 1}$

Hence, your answer is 15m/s.
