If the speed of Y meters per second is equivalent to the speed of X meters per hour, what is X in terms of Y? (1 kilometer=1000 meters)  Options:  A) 15y/18  B) 6y/5  C) 18y/5  D) 3600y  E) 3600000y
If the speed of Y meters per second is equivalent to the speed of X kilometers per hour, what is X in terms of Y? (1 kilometer=1000 meters)   We need to find an equation with y in the answer...   convert all measurements so they are alike (i.e. convert km to m, seconds to hours, etc)   Speed = y/t   y meters/second   (3600) x meters/hour   Speed = x/t   x KM/hour   Speed = x/hour   x/hour = (3600) x meters/hour   x/1hour = y(3600) / 1 hour   x = y(3600)   x = 3600y   Answer: 3600y.
