What is the average speed of a jet plane that flies 7200 km in 9 hours?
The speed of a cruise ship is 50km/hr. How far will the ship travel in 14 hours?
A car accelerates from 0 km/hr to 60 km/hr in 5.0 seconds. What is the car’s acceleration? (watch the units!)

   distance = velocity * time

   7200km = veloicty * 9hr
   velocity = 800km/hr

   distance = (50km/hr)(14hr)
   distance = 700km

   Vf = at + Vi

   change to m/s
   60km/hr => 16.67m/s
   16.67 = a(5) + 0
   a = 3.33m/s^2

   hope this help.
