a high speed train between shin-obuku and tokyo averages 284.5 km/hr. If the trip takes 0.8 hours, how far apart are the cities? What would the trains speed be in m/s?
We can use the distance, rate, and time formulas.
We know that
r = d/t
d = r * t
We have both the rate, and the time.
284.5 * 0.8 = 227.6
Therefore, the cities are 227.6 km apart.
