Hi there! :)

Answer:

`\huge\boxed{522 km/hour}`

`\text{Express 145 m/s as a fraction:} (145m)/(s)`

`\text}Convert to km/hour by multiplying by the equivalents in terms of meters and seconds to cancel out the units}`

`(145m)/(sec) * (3600 sec)/(1 hour) * (1 km)/(1000 m) = \\\\\text {Cross out similar units and multiply the coefficients:}\\\\(145 * 3600 * 1km)/(1 * 1hour * 1000) = (522000km)/(1000hour)= 522 km/s.`
