Question

Erica and Amy start biking in the opposite direction at the same time. Erica picked at a speed of 6 meters and Amy picked at a speed of 4 meters per second. how soon were they exactly 1 km apart?

Answer 1

Three deficiencies:

 

1. Erica picked?  Amy picked??

2. Erica and Amy start biking in the opposite direction?  Probably they biked in opposite directions (plural). Do you see the error there?

3.  You submitted this question two times in a row! Other one was answered by Arturo.
