Question 210937
let x be the distance to parents house. 
75x = 65(x+30)
75x = 65x+1950
10x = 1950
x= 195 
unfortunately, when I check my work by substituting 195 for x on both sides of the equation, the answers aren't equal to eachother. where did I go wrong?
-----------------
The speeds are miles/hour, but the 30 is minutes.  
let x be the distance to parents house. 
75x = 65(x+0.5)
75x = 65x+32.5
10x = 32.5
x= 3.25 miles
----------
Check:
75*3.25 =? 65*3.75
