Asked by Peter G.

Can someone help me with a formula for this?

A container ship left the Azores and
traveled north. An aircraft carrier left two
hours later traveling 5 km/h faster in an
effort to catch up to it. After eight hours
the aircraft carrier finally caught up.
What was the container ship's average
speed?
Answered by Reiny
rate of container ship ---- x km/h
rate of carrier ------- x+5 km/h
after 8 ours, carrier caught up, they went the same distance.
10x = 8(x+5)

solve for x
