Ahelicopter leaves an airport and flies south at 180 mi/h. thirty minutes later, an airplane
leaves the airport and follows the same route as the helicopter, only at a higher elevation. the
airplane is flying 330mi/h. how many minutes will it take for the airplane to catch up with
the helicopter? (hint: 30 minutes is hour.)

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
