Suppose part of the Diaz family goes into one balloon and other members go into another balloon. Because they are flying at different altitudes and carrying different weights, one balloon travels at 14 miles per hour while the other travels in the same direction at 11 miles per hour. In how many hours will they be 12 miles apart?

Question

difference in their speeds is 3 mph so how long does it take to travel 12 miles at 3 mph?  divide distance by rate to get the time

anonymous · Answer

there is no equation, only arithmetic 
$14-11=3$ and 
$12\div 3=4$

anonymous · Answer
