Acontainer ship left the pier and traveled toward a marina an aircraft carrier left six hours later traveling 9km/h faster in an effort to catch up to it. after 4 fours the aircraft carrier finally caught up. find the container ship's average speed.

  6 km/h

Step-by-step explanation:

After 4 hours at a speed difference of 9 km/h, the carrier made up a distance of ...

  (4 h)(9 km/h) = 36 km

This head start was achieved by the container ship in 6 hours, so it speed was ...

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
