John drives from his house to the forest. The distance between his house and the forest is 873 meters. His average speed while driving is x km/hr. Write down an expression in terms of x for the number of hours it will take him to drive to the forest.

Sagot :

Distance divided by the Average Speed is the formula for this problem but since x is not given and you are asking for a expression, the expression will be Distance / Average Speed.
If 1 km/hr = 1000 m/hr, then x km/hr = 1000x m/hr.
d = 873m        s = 1000x m/hr
t = d/s
  = ( 873m ) / ( 1000x m/hr )
  = ( 873 ) / ( 1000x hr )  ( cancel "m" )
t = 873/1000x hr
Therefore, he traveled 873/1000x hrs.
