Acontainer ship left the dania pier and traveled toward a navigational buoy. an aircraft carrier left 0.7 hours later traveling 1.4 km/h faster in an effort to catch up to it. after four hours the aircraft carrier finally caught up. what was the container ships average speed?

Average Speed of Container ships is 8 km/h.

Step-by-step explanation:

Let the Average speed of container ship be 'x'

Now Given:

An aircraft Carrier left 0.7 hours later traveling 1.4 km/h faster in an effort to catch up to it.

Hence speed of aircraft carrier =

After four hours the aircraft carrier finally caught up container ship.

Hence Total time taken by aircraft = 4 hrs.

Since aircraft left after 0.7 hours and after 4 hours it caught the container ship.

Hence time taken by Container ship = 4 + 0.7 = 4.7 hrs.

Now we will find the Distance traveled by both.

Distance can be calculated by product of time and speed.

Distance of aircraft =

Distance of container ship =

Since both of them are at same place hence distance travveled by both would be similar.

Hence,

Distance of aircraft = Distance of container ship

Substituting the values we get;

Hence Average Speed of Container ships is 8 km/h.
