Question 651801: An aircraft carrier left the Pier 53 and traveled north. An container ship left 1 hour later traveling at 3km/h faster in an effort to catch up to the aircraft carrier. After traveling for 5 hours the container ship finally caught up. What was the aircraft carrier's average speed? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! An aircraft carrier left the Pier 53 and traveled north.
A container ship left 1 hour later traveling at 3km/h faster in an effort to
catch up to the aircraft carrier.
After traveling for 5 hours the container ship finally caught up.
What was the aircraft carrier's average speed?
:
Let s = the carrier's speed
then
(s+3) = container ship's speed
:
When the container catches the carrier, they will have traveled the same dist
Write a dist equation; dist = time * speed
The carrier traveled for 1 hr longer, 6 hrs
6s = 5(s+3)
6s = 5s + 15
6s - 5s = 15
s = 15 km/hr is the carrier speed
:
:
Check this by finding the distances
Carrier: 6(15) = 90 km
Container: 5(18) = 90 km
