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.
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.
