Car 6 truck 10 suv 14 minivan 15 at this rate if 150 vehicles passed luann how many more mini vans than cars would pass her

number of minivans more than number of car =  30

Step-by-step explanation:

we have the rate of number of vehicles passed in one unit of time

Number of cars = 6

Number of trucks = 10

Number of SUV = 14

and number of minivan = 15

Total vehicle passed in one unit of time = 6+10+14+15 = 45 vehicle per unit time.

we can see the ratio of vehicles with each other can be given as:

6x+10x+14x+15x = 150  

Now we can solve for x to get the number of cars and minivans in 145 vehicles.

or 45x = 150

or x = 150÷45 =

so, number of cars in 150 vehicles = 6x = 6× = 20 cars

number of minivan in 150 vehicles = 15x = 15× = 50  minivans.

So, number of minivans more than number of car = 50 - 20 = 30
