Question 767874: Curtis and Karly are riding bicycles in the same direction. Curtis is traveling at 4 miles per h,our and Karly is traveling at 9 miles per hour. In 3 hours, what is the distance between them?
Answer by algebrahouse.com(1659)   (Show Source):
You can put this solution on YOUR website! Distance = rate x time
Curtis' distance = 12 miles {rate x time}
Curtis' rate = 4 mph
Curtis' time = 3 hours
Karly's distance = 27 miles {rate x time}
Karly's rate = 9 mph
Karly's time = 3 hours
In 3 hours Karly will have traveled 27 miles and Curtis will have traveled 12 miles.
Therefore, the distance between them, after 3 hours, will be 15 miles.
