Question 247177: A car travels from one town to another at a speed of 32mph. If it had gone 4mph faster, it could have made the trip in 1/2 hr less time. How far apart are the towns? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 32x=d
36(x-1/2)=d
32x=36(x-1/2)
32x=36x-18
subtract 32x from both sides
0=4x-18
add 18 to both sides
18=4x
4.5=x
