Question 1072447: Erica and Amy left the park riding their bikes in opposite directions. Erica biked at a speed of 6 m/sec and Amy biked at a speed of 4 m/sec. How long after they left the park were they 1 km apart Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Erica and Amy leave the park going in opposite directions, so the distance between them grows at 6+4, or 10 m/s. So:
1000 m/10(m/s)=100 seconds before they are 1 km apart. ☺☺☺☺
