A car travels from one town to another town at a speed of 18mph.
If it had gone 18mph faster, it could've made the trip in a half hour less time.
How far a part are the towns?
:
let d = dist between towns
:
Write a time equation: time =
Actual speed time = 18 mph faster time + half hr
= +
multiply equation by 36, results
2d = d + 18
2d - d = 18
d = 18 min between towns
;
;
Check solution find the times
18/18 = 1 hr
18/36 = .5 hr
-------------
diff = .5 hr
