Question 1194543: Two cars are travelling in the same direction on the road. The car that leads is travelling at 46 miles per hour. The other car is travelling at 70 miles per hour. How many miles apart will they be 30 minutes before the faster car catches the slower one? Answer by greenestamps(13198) (Show Source):
The difference in speeds of the two cars is 70-46 = 24 miles per hour.
In 1/2 hour, the distance between the two cars changes by (1/2)*24 = 12 miles; so 1/2 hour before the faster car catches up to the slower car the two cars will be 12 miles apart.
