Question 250724
Start with the plane...65% of 1800  would be 1800 x 0.65 = 1170
Then the train ...20% of 1800  would be 1800 x 0.20 = 360

add 1170 + 360 = 1530  now subtract 1530 from 1800

so:  1880 - 1530 = 270

Therefore there will be 270 km traveled by road.

I apologize..it is in Kilometers.

As for the other question:  to find a percentage, you divide the number by the total and multiple by 100.

So 140 divided by 2000 = .07 then times 100 = 7%

Subtract 7% from 100% and you get 93%  there fore 93% it getting through.
