Step-by-step explanation:
6/4=1.5 (price per can)
10/8=1.25 (price per can)
1.25 is cheaper than 1.5
the second one is the better buy
55t+285t=1020 combine like terms on left side
340t=1020 divide both sides by 340
t=3 hours
However that t is for the amount of time spent on the train and the same amount of time spend on the plane. So the total time for the trip is 2 times t, which is:
6 hours.
