# For the carriage of cargo, a car with a carrying capacity of 7.5 tons had to make 12 trips.

**For the carriage of cargo, a car with a carrying capacity of 7.5 tons had to make 12 trips. How many trips will have to be done by a car with a carrying capacity of 9 tons to transport the same cargo.**

Let’s find the amount of all cargo that was transported by the given first car, for this we need to multiply the value of the carrying capacity of the given car by the number of trips that the given car made to us:

7.5 * 12 = 90 tons – this is the mass of all cargo transported by this vehicle;

Let’s find the number of flights that the second car given to us will make, for this we need to divide the mass of the entire load by the value of the carrying capacity of the second car given to us:

90: 9 = 10 trips must be made to the second car given to us in order to transport the entire cargo.

Answer: 10 flights need to be made to the second car given to us in order to transport the entire cargo.
