Samson is going to another town which is 140 km away. He will use his car that uses ten liters of gasoline for a distance of 70 km. How many liters of gasoline will Samson need for a one-way trip?
Samson will need 140 km/70 km = <<140/70=2>>2 ten liters of gasoline for a one-way trip to a town.
Therefore, he will need a total of 2 x 10 liters = <<2*10=20>>20 liters of gasoline.
