Question

A jet flies 600 kilometers in 3/4 hour. How far can the jet fly in 1 2/3 hours?

Answer 1

600 = 45x  (x= minutes) 
13.3333333=x 

1*(2/3) = 80 minutes 

80x= 13.333333*80

Therefore the airplane flies 1066.66664 km in 80 minutes or 1 2/3 hours

Answer 2

if 600=3/4 then you divide both by 3 and you get 200=1/4 do fine unit rate multiply both sides by 4 and you get 800km/hr divide 800 by three to get one third of it (266 and 2/3) then multiply it by two (533 and 1/3) you must add the two thirds to the one to get 1333 and one third.
