Answer :
you need 3 trucks of sand that hold 5 tons and 2 trucks that hold 3 tons to move all the sand in one trip
Well you need three trucks that can pull 5 tons of sand each; that gives us 15 tons total taken care of so far, and 2 drivers left.
The last two drivers drive two trucks that pull 3 tons of sand each; giving us a total of 21 tons and zero drivers left.
Hope this helps!
