Answer:
50 cars and 25 bikes
Step-by-step explanation:
Given
Total wheels = 250
Required:
Number of cars and bikes
Let C represent Cars and B represents Bike
A car has 4 wheels and a bike has 2 wheels;
So,
Divide through by 2
---- Equation 1
The ratio of wheels of cars to wheels of bike is 1:2
Meaning that
1C = 2B
So, C = 2B
Substitute 2B for C in equation 1
Divide both sides by 5
Recall that C = 2B
So,
Hence, Anna has seen 50 cars and 25 bikes
