Problema Solution
denver and moises live 90 miles apart. if they leave their homes at 10:00 Am and drive toward each other, how many miles apart will they be at noon, if denver drives at 10 miles per hour and moises drives at 30 miles per hour?
Answer provided by our tutors
The time that they will spend traveling from 10 am till noon is 12 - 10 = 2 hours.
In 2 hours Denver will pass 2 * 10 = 20 miles
In 2 hours Moises will pass 2 * 30 = 60 miles
Since the total distance between them is 90 miles, after 2 hours they will be 90 - (20 + 60) = 10 miles apart.
