Question 1203653
<br>
You have received two responses showing a standard algebraic method for solving the problem.<br>
Here is a solution using a very different method.<br>
The two speeds are 25mph and 30mph, a ratio of 5:6.<br>
Since the distances are the same, the ratio of times at the two speeds is 6:5.<br>
The time at the higher speed is 1/2 hour less than the time at the lower speed.<br>
x = hours at lower speed
x-1/2 = hours at higher speed<br>
The ratio is 6:5<br>
{{{x/(x-(1/2))=6/5}}}
{{{6(x-(1/2))=5x}}}
{{{6x-3=5x}}}
{{{x=3}}}<br>
The time spent at the lower speed was 3 hours.  Since the lower speed was 25mph, the distance was 3*25 = 75 miles.<br>
ANSWER: 75 miles<br>
