Answer:
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
