Question 1005925
Two cars leave a city and head in the same direction. 
After 3 hours, the faster car is 18 miles ahead of the 
slower car. The slower car has traveled 150 miles. Find 
the speeds of the two cars.
<pre>
The slower car has traveled 150 miles in 3 hours.
So the slower car's speed is 150 miles in 3 hours or 
150 mi per 3 hr, or (150/3) mi/hr or 50 mi/hr.

The faster car has traveled 150+18 or 168 in 3 hours.
So the faster car's speed is 168 miles in 3 hours or 
168 mi per 3 hr, or (168/3) mi/hr or 56 mi/hr.
