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.
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.
