Equation Km - m

by szDave » Thu Jan 24, 2013 6:53 am
If the speed of x meters per second is equivalent to the speed of y kilometers per hour, what is y in terms of x? (1 kilometer = 1,000 meters)

Answer: [spoiler]18x/5[/spoiler]

Please give me an explanation, thanks!

this is a measurement problem. Convert accordingly:

x meters/ second * 3600 seconds / hour * 1km / 1000 m = 3600x km / 1000 hr = 18x/5

y = 18x/5
